Pro Built-in physics system
Thanks to the great power of Erin Catto's Box2D, Construct 2 is able to make physics games which are similar to Cut the Rope and Angry Birds.
Pro Supportive community
Construct 2 has a supportive community. Their forums have tens of thousands of topics with ten times more posts. The core maintainers are very helpful and friendly and often reply to questions or issues that may be discussed in the forums.
Pro Little programming knowledge needed
Using Construct 2 requires very little programming knowledge because it's all drag'n'drop, intuitive, visual and event-driven instead of code-only.
Pro Easy to create particles and animations
With spriter file implementation and internal animation editor Construct 2 provides an easy way of creating particles and animations.
Pro Free (feature limited) version available
A free version of Construct 2 is available. It's not time restricted in any way, but is feature limited.
Pro Export control for all major platforms
All platform exporters are part of the subscription. There are no additional fees and new exporters are added quickly and maintained well. Currently, 15 platforms are supported, including HMTL 5, iOS, Android, Windows, Chrome Store, PhoneGap and Scirra.
Pro Built in behaviors make development workflows very efficient
Behaviors add pre-packaged functionality to object types.
Pro Active plugin ecosystem
Construct 2 has an active plugin ecosystem providing behaviors and features that smooth the workflow for certain game types.
Pro In-depth event system
Construct 2's event system allows for deep, detailed control over all aspects of your game. You aren't limited to just a few options. Rather, Scirra has thought of nearly everything in advance with access to any desired parameter of any object all paired with simple and intuitive ways to interact with them.
Your events can be organized with event sheets (that can be included in other sheets), event groups, sub-events, loops, and functions that make the coding portion of your game as efficient as possible. You don't need any programming knowledge, but if you do have some, you'll feel right at home with the freedom C2 offers.
Pro Available on Steam
You can also download Construct 2 on Steam.
Pro One-off cost
It's a one off cost for Construct 2 and all updates to the Construct 2 editor are free for life.
Pro Supports camera, microphone, speech recognition and synthesis
Can use cameras in PCs and on mobiles. You can use the synthesis that can recognize your speech or you can write something and it can talk for you.
Pro Very fast preview
In Construct 2 you can preview your games instantly at any time. There’s no need to wait for compiling or other time consuming processes.
Pro Interface similar to that of MS office
This engine provides an intuitive workflow for people that are used to the Windows environment.
Pro Runs great on mobile
Performs well on most devices and browsers.
Pro Rapid development
After using a few quick tutorials you can quickly catch on to the event system this program uses and quickly be able to build any type of 2D game you want. You can download a few sprites from google and put together a working level of Mega Man with character movement / animation / enemies / collision detection / scoring / Tile map and AI within about 2 hours.
The built in behaviors are incredible. It's amazing how Construct can simplify the most redundant tasks in game development.
Pro Allow server-less multiplayer game creation
Construct 2 uses WebRTC technology to support it's multiplayer functionality. The nature of the technology allows peer-to-peer connection which does not require game developer to create server side architecture to allow communication between games.
Pro Supportive devs
The developers are always available to help.
Pro Built-in animation/image editor
Basic sprites and tiles of 2D games can be made with engine's built-in tools.
Pro Built-in pathfinding
Has built-in solutions for pathfinding.
Pro Built-in tilemap object
The tilemap object allows tile-based games to be designed more easily. The object's tilemap can also be edited in the layout view using the tilemap bar.
Pro Simplicity - it is made for everybody to use and love
Construct 2 is a tool for not just programmers, but artists as well. You can create a game with only visual coding, which is easy to learn and doesn't require any previous programming knowledge. You can focus on making your game better instead of just coding. It has some limitations of course, but it's definitely worth it.
Pro Cordova support
You can use Cordova plugins from the community
Con Learning curve for hobbyist developers
Hobbyist developers coding alone may experience a learning curve with Allegro of about 200 hours (if you are rusty on C++). To learn quickly, see Mike Geig's tutorials at Fix By Proximity. This learning curve may be fine if you are considering going professional, but are still unsure.
For hobbyist developers not planning on going professional, you may want to look into a complete 2D game engine, rather than a coding library. For example, there are "non-coding" engines that provide support for coded plugins or scripting. But, if you are a dedicated hobbyist planning to use Allegro as your coding library of choice, you can still develop great games as a hobbyist.
Con Isn't great for C++
If you are a fan of object oriented programming, and want to use this library, then the chances are that you are going to be creating a lot of wrappers for functions in this library.
In short, if you're a C++ person, it could be recommended to check out SFML instead.
Con Does not export to native mobile code
Construct 2 builds to HTML 5 only, which can cause performance issues on mobile devices depending on the HTML5 engine that the OS is using since that will be the biggest bottleneck. Even though it's not really the engine's fault, it still is at a disadvantage compared to native game engines.
Con Poor mobile performance
Con The editor is Windows only
Although Construct 2 is able to export projects to Windows, OS X and Linux, the program itself currently only runs on Windows.
Con HTML5 is very dependent on browser performance
Theoretically all browsers should run HTML5 pretty much the same way, but thats not always the case.
Something that worked fine on Chrome, for instance, might malfunction on Firefox (or vice versa). And there's nothing the devs of Construct 2 can really do about it, but to hope next Firefox update might fix it. Internet Explorer is not even recommended.
Add to that the fact that exporting to mobile or desktops rely on these sort of stripped down versions of web browsers (Node webkit, Crosswalk, Ejecta) that you pack with your game, and you can have a real headache if you're trying to make your game work properly through multiple platforms.
Con Dependency on 3rd parties for all exports
Unless you are creating a game strictly for browser/HTML5 usage, exporting to desktop or mobile is risky, as Scirra have no control over your final export quality. Since desktop uses NodeWebkit and mobile is Crosswalk, Phonegap or CocoonJS there is no guarantee that your final export performance and quality will be up to scratch for pro level 2d games. These 3rd party "browser wrappers" are very prone to breaking and introducing lag and bugs that can't be controlled from Scirra's side.
Con Free version is severely limited
Although a free version of the engine is available, it lacks features that are essential to creating a high quality product.
Con Poor business model
Non-competitive pricing structure with limited license options. Favorable perpetual license dropped for non-favorable subscription service and highly restrictive feature set under new banner. Company does not take criticism well, sometimes becoming threatening over unfavorable feedback.
Con HTML5 Only is extremely limiting
If the software could export natively to mobile devices and PC/Mac/Linux it would be extremely powerful. The developer's choice of sticking to only HTML5 has created a bottleneck for anyone wanting to develop with this software.
Con Tilemap object could be better
C2 requires that there's a tilemap objects for each tilemap layer meaning each tilemap object has to be updated when modifying any layer. This could be simplified by adding layer support for tilemap objects.
Con Clickteam Fusion Clone
This is a copy of the Clickteam softwares
Experience regular crashes and inexplicable project file corruption.
Con Unreliable access to online resources
Unreliable access to online resources such as online tutorials and forums, plus extremely outdated offline manual.
