Felgo (formerly V-Play) vs HaxePunk

Qt-Creator IDE with Code Completion, Debugging and Profiling, integrated Quick Help, Version Control and more.

Felgo is among the easiest cross-platform tools to use according to a survey done by research2guidance.

With the Level Editor components, you can let your players share their levels with the whole game community which is cool because you don't need to create new levels on your own, but the community helps you with it. There are other community features like rewards for good level creators that helps getting more downloads.

Leaderboards, Achievements, Challenges are available across platform, even on Desktop. You can also use Cloud Syncinc of your game data that makes it easy to start a game for example on iPhone and then continue on a Nexus Tablet or the other way around.

It is also convenient because sharing to all kind of game services & networks like Facebook & Game Center is possible with a single API call. Custom hosting of Game Network servers is also possible if you want to keep the player data.

Although game logic is provided in JavaScript by you, performance-critical parts of the engine like OpenGL ES rendering or particle effects are implemented in rock-solid C++, providing the ultimate performance your game deserves.

Advanced Gaming Components for handling multiple display resolutions & aspect ratios, animations, particles, physics, multi-touch, gestures, path finding and more.

No need for native SDKs, Build in and Install from Cloud with the Felgo Build Server.

Cut your development time in half. Using the QML language allows for some powerful features that cut code lines and time. Another helpful feature that can help in this area is that there are more than 50 game demos of all genres that come with full source code, meaning one can easily check to see how something was done.

Felgo has friendly forums where core developers participate as well as fast & helpful email support.

The Qt framework is a great and mature framework on its own. Using Qt as a game engine base is a smart idea.

You can use ready-made components to balance any of your game properties at runtime, so also on mobile devices which is great for adjusting forces or input parameters.

Helps get started and improve with lots of tutorials, demo games, examples.

In-app purchases, game and social network integration (such as Game Center and Facebook), ads (with Chartboost and AdMob) and analytics (such as Flurry) are all available across platforms.

Every 2-4 weeks new updates provide additional features and fixes based on what users wanted the most.

You can even monetize these user-generated levels with in-app purchases with the Felgo Level Store component if you like.

Useful for mobile games and soon consoles (OpenFL has a console port in the works).

HaxePunk uses OpenFL which means you can compile to just about every device. A lot of the rendering code has been optimized so if you use HaxePunk’s graphic classes you are pretty much ready to deploy on any target.

A generic Entity system that only uses what you “attach” to it. If you need collision masks they are available but if an entity doesn’t need to collide with anything then simply don’t add a mask. Same goes for graphics.

This comes with blazing fast compile times, proper static typing, multiple output targets, and a powerful macro system.

HaxePunk has added several collision masks beyond what FlashPunk had including a grid with slope values, circles, and polygons. This is in addition to FlashPunk’s tile grid and hitbox.

Tweens are available just like they are in FlashPunk. If you need to interpolate values for sounds, movement, etc… it’s probably already available as a tween. There is also a VarTween that lets you interpolate any value you want.
