Every property can be animated.
Ranked in these QuestionsQuestion Ranking
Pro Great for prototyping
The framework is focused on prototyping. It has plenty of features to speed up development. It has a console with a lua interpreter, tuning variables and function calls. GWEN is well supported. Provides a simple interface for Box2D. A simple messaging system with which entities can subscribe to to receive messsages among other things.
Pro Permissive licence and easy to extend
Angel2D is built with the idea that you the game developer should have control over the framework and be able to add features if you like. So the code is BSD-licenced and very easy to extend for anyone that has completed a basic C++ course or equivalent.
Pro Great performance
While Angel2D isn't the best performing framework out there it's certainly no slog when compared to competition. Simply by the virtue of being native it puts itself ahead of engines like Gamemaker and frameworks like Love2D.
Pro Simple interface to lua scripting
If you're not comfortable with a basic subset of C++ it is not recommended to use this framework. But the Lua scripting platform is very nice for generating actors.
Pro Very helpful and simple project set up for newcomers
Often with game engines they throw you into unfamiliar territory and let you explore for yourself. While this wouldn't be a big issue with Angel2D due to it being a very simple framework it kickstarts your game prototyping.
Pro Focused on providing convenient features
Angel was created with game jams in mind, so it's focused on providing as many convenient features as possible, but in a quickly understandable way.
Pro Cross platform
Angel can create games for Windows, the Mac, most flavors of Linux, and iOS. It uses the native build systems on each platform (Visual Studio, Xcode, Make), so you can be up and running as soon as possible.
Pro Low-level code is easily accessible
Low-level code that Angel wraps is always just an easy click away, ready to be overridden or improved.
Pro Very light wrapping on all of the libraries
A very important point that's often underestimated. This framework is designed to be removed. It's not there to provide a complete engine for you which you will have trouble moving away from. The basic interface to Box2D is very spartan. You're given the simplest of Box2D shapes, not even polygonal fixtures. This limitation (seems to be) there so that the integration with the engine is very low. You never create a physics actor with anything more complicated than an enum describing if it's supposed to be a sphere shape or box shape.
Pro Integrated animation editor
Every property can be animated.
Pro Unified game editor interface
All the game developing work is done inside one program: the engine editor. This feature is something only high end engines have. Even the scripting is done in the same program. No need for Eclipse or other front end editors.
Pro Can be deployed to multiple platforms
Deploy games to desktops (Windows/OS X/Linux), smartphones (iOS/Android/BlackBerry), and the web (HTML5 via Emscripten).
Pro Fully dedicated 2D engine, no hacks
Godot has a mature 2D engine with many features used by modern 2D games.
Pro Built-in physics
Add physics to 2D and 3D scenes, through rigid and static bodies, characters, raycasts, vehicles and more.
Pro Under constant development
This engine barely released one year ago has more than 1000 forks on github and about 100 developers. Not only that just a bit of browsing trough issues you will quickly find out the dev community loves new esp free technology and does not shy away from completely rewriting parts of the engine. The audio engine is being completely rewritten to use threads and so forth.
Pro Free and open source
Godot is licensed under MIT license. Anyone can grab the source from https://github.com/godotengine/godot, and compile the engine themselves.
The executable is portable and less than 40 MB in size.
Pro Editor and runtime are fully cross-platform
You can run Godot on all 3 major operating systems (Windows/Mac/Linux) and build your game to all available platforms from each without any platform-specific work needed. All platforms including Linux are supported first class.
Pro The list of supported languages is growing
Officially, Godot supported languages for now will be GDScript, C#(Mono), VisualScript and C++.
Pro Fun to use
An important aspect that can't be grasped without using the engine for a few days. The Interface is evolving nicely and making games is just fun.
Pro Easy to learn scripting language
It can be used to add custom behaviors to any object by extending it with scripting, using the built-in editor with syntax highlighting and code completion.
A built-in debugger with breakpoints and stepping can be used and graphs for possible bottlenecks can be checked.
Pro Internationalization of the editor
You can change the language shown in menus. Godot translations: https://hosted.weblate.org/projects/godot-engine/godot/
Pro User friendly UI for all your team
Non-programmers (musicians, artists, etc) can join the development easily.
Pro Instancing and node concept makes sense
The node and the instancing concept work very well and helps developers to structure content efficiently.
Pro Drag & drop interface
Many parts of the editor allow you to drag & drop, which makes working with assets and scene trees a joy.
Pro Friendly towards Version Control Systems
The engine is build not only to support version control but to really use it. Scene files for example which usually get compiled into some sort of unreadable data stay in a text format - that way you can actually see your changes in a version control system like Git.
Pro Really good community
The community is great and really cares about the engine. It is easy to get help and to be part of Godot's future.
Pro Simple and readable codebase
The engine's source code is easy to read and understand with a self-documenting approach to code design. You don't have to wait months or years for other people to fix an engine bug that is important to your game. Often times, you can spend an hour or two of your own time to fix whatever problems you encounter yourself.
Pro Built-in documentation linked to the internal ScriptEditor
The editor has a fully searchable index of class API documentation for everything the engine offers (NOT just a web interface). You can easily open the documentation for any class by Ctrl-clicking the class's name in the in-engine text editor for scripts.
Pro Creating editor tools is a breeze
Godot Engine is itself a Godot game. By adding the "tool" keyword to the top of a script, you can design extensions for the editor itself INSIDE the editor. Integrating these editor scripts into a bundled plugin for sharing is extremely easy to do.
Pro Easily expanded scripting system
With 3.0's addition of NativeScript and PluginScript via GDNative, developers can easily define bindings for new scripting languages. In addition to the primarily supported C++, GDScript, VisualScript, and C# languages, the community has contributed D, Nim, and Python as well with more on the way.
Con No asset pipeline
Unlike XNA/Monogame, Gamemaker or many other similar platforms, Angel2D doesn't have an asset pipeline. The extents of the asset importing is manually loading individual files in code or naming them according to a convention to load a set of them.
Con No longer supported
Hasn't been updated in 2 years.
Con Incomplete documentation
The entire framework is technically documented at http://docs.angel2d.com/ but certain functionality isn't described in there but rather it's just a list of functions. They all have descriptive names and it should be common to run into a feature which isn't given example to in the "Introgame"-project example.
Con Abandoned by developers
Sadly this project has been abandoned by the developer. The main github doesn't see any pull requests fulfilled anymore. There's a debugline draw fix on the github that's rather simple to fix. It is recommended you pull that fork rather than the master branch. Though the simplicity of the framework still makes it a good choice for prototyping.
Con Tileset management could be more efficient
The tileset creation and management is lacking common features found in more developed tileset managers. However, it features support for Tiled - the only downside being that it is an external program.
Con Very bad documentation
The documentation is poorly written, and has very few examples of real application and even fewer design guidelines about how to program a game in the engine.
Con No built-in way to import atlases
Godot does not have an easy and automatic way to import atlases created by other tools. However, there are plugins that can be used to import atlases from other engines.
Con 2DPhysics is weak compared to Box2d
Box2d has much more features.
Con Difficult to optimize
Godot has an OOP architecture. Everything is an object internally and data is spread among many classes, thus it's difficult to optimize (i.e. not cache friendly, difficuly to vectorize or paralellize, etc).
Read about "Data Oriented Design" for more info about the problems and solutions.
Con NoAdmob or other AdNetwork support
Godot has no native support for implementing advertisements into your game.
Con OSX app is a mess
Instead of one contained folder/file with an icon per normal it is a mess of files which is not at all suitable or distributable without further work after every compilation.
Con Hard for a Unity user
Coming from a Unity background, Godot engine is hard.
