Orx vs Felgo (formerly V-Play)

Powerful config system that makes orx data-driven and provides an easy to use load/save system.

Good friendly development community ready to help each other with tips and advice for setting up and best practices.

Automatic hot-loading of resources upon modification on disk, shortens drastically iteration times.

Written in C with high emphasis on memory and CPU efficiency.

Supports Windows, Linux, Mac OS X, iOS and Android.

Orx is a Data Driven engine that greatly reduces required code. You can configure object definitions, bodies, cameras, sound, animation, event tracks, etc.

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.

Clock system that provides time consistency and allows time stretching + high precision timers

Color and translation FX are simple to configure and apply to objects.

Includes a chaining graph & custom animation events for synchronization.

Uses the zlib license. Lets you use Orx for free for any kind of projects, even for commercial ones.

All input devices are fully supported: Joysticks, Mouse, Gamepad, Keyboard and Touchscreen. Multiple physical devices and be mapped the same binding.

Rated the fastest engine in the OpenFL’s BunnyMark since October 2015.

Samples for sound effects, or streams for music. All sounds can be groups via audio buses just like in a typical DAW (Digital Audio Workstation).
All sounds can be spatial relative to the camera.

Camera/viewport scheme allowing multiple views displayed with camera translation, zoom and rotation.

Fragment (pixel) shader support, render to texture, MRT, easy composition and custom rendering support.

Integrated runtime profiler (with graphical display) to easily spot which parts of your game need to be optimized.

Supports .bmp, .png, .jpg, .tga and .dds

Orx provides a excellent c++ wrapper for object oriented design, called: orx/Scroll. You can, of course, roll your own.

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.
