Automatic hot-loading of resources upon modification on disk, shortens drastically iteration times.
Pro High performance
Written in C with high emphasis on memory and CPU efficiency.
Pro Supports desktop and mobile
Supports Windows, Linux, Mac OS X, iOS and Android.
Pro Data configuration
Orx is a Data Driven engine that greatly reduces required code. You can configure object definitions, bodies, cameras, sound, animation, event tracks, etc.
Pro Custom shader support
GLSL code can be added straight into data configuration files and can be applied to any texture: background or objects whivh allows for some amazing effects. All GLSL versions are supported, again by providing the shader language version in your configuration file.
Parameters are supported and values over time for shader animation.
Pro Flexible clock system
Clock system that provides time consistency and allows time stretching + high precision timers
Pro Flexible and simple FX
Color and translation FX are simple to configure and apply to objects.
Pro Good animation engine
Includes a chaining graph & custom animation events for synchronization.
Pro Free and open source
Uses the zlib license. Lets you use Orx for free for any kind of projects, even for commercial ones.
Pro Input controls and binding
All input devices are fully supported: Joysticks, Mouse, Gamepad, Keyboard and Touchscreen. Multiple physical devices and be mapped the same binding.

All sounds can be spatial relative to the camera.
Pro Viewport scheme allowing multiple views
Camera/viewport scheme allowing multiple views displayed with camera translation, zoom and rotation.
Pro Good render support
Fragment (pixel) shader support, render to texture, MRT, easy composition and custom rendering support.
Pro Easy post-processing/compositing for complex visual effects
Pro Integrated runtime profiler
Integrated runtime profiler (with graphical display) to easily spot which parts of your game need to be optimized.
Pro Collision handling and rigid body physics
Pro Screenshot capture tool

Pro Easy to learn
Defold uses Lua, which is regarded as an easy to learn language by most.
Pro Completely free of charge
Software and online dashboard are free of charge.
Pro Good combination of visual editing + code (Lua)
You can do a lot with drag and drop, but you're not limited -- the code (Lua, which is easy to learn) allows you more power than just visual editing usually gives you.
Pro Fast results
Going from idea to result is very important for the creative process.
Pro Visual editor
Pro Very performant
Being crossplatform it is important to work on low end devices.
Pro Easy and fast export for various platforms
Pro Great community

Pro Source code available
You can download and modify the source code of the Editor and the engine for free.
Pro Collaborative
You can invite friends from the dashboard and create games together.
Pro Hot reload
It allows you to change scripts in a game while it is running live. Common use-cases is to tweak gameplay parameters or to perform debugging on a running game.
Cons
Con Feature discovery and explanation could be better
Some features are not well explained / highlighted: for example, unless you use the interactive project initialization, you have to go over the tutorials and examples in the wiki to learn that there is an optional C++ layer, Scroll, developed on top of the C API. Similarly, some major information are missing from the website, wiki and Doxygen documention, and are left for the users to discover in source headers and INI template files, or by searching the forum (e.g. the 0,0 coordinate being the center of the screen and not top left, the list of all Orx scalar types and their use, etc).
