VVVVVV
The source code to VVVVVV
From the creator of Super Hexagon, VVVVVV, the hit 2010 indie platformer, now available on android and iOS! Winner of Indiecade's 2010 award for Most Fun/Compelling Game. There are two versions of the VVVVVV source code available, the desktop version (based on the C++ port, and currently live on Steam), and the mobile version (based on a fork of the original flash source code, and currently live on iOS and Android). If you’re looking for the game’s text, that’s mainly (but not entirely) in the Scripts.cpp and TerminalScripts.cpp classes. These functions basically load data into a very simple script parser that controls cutscene logic. All the actual levels in the game are hardcoded in huge arrays generated with a map editor, which exports the levels in source code. Since the 2.0 update, the Windows, Mac and Linux versions of VVVVVV have featured a powerful and easy to use level editor. -

bfxr
Flash + AIR sound effects generator. Based on Sfxr.
The bfxr project by increpare is a sound-effects generator tool originally built using Flash + AIR, based on the earlier Sfxr project. Its purpose is to enable users, especially game developers and sound designers, to quickly generate retro, 8-bit/“chiptune” style sound effects (“bleeps”, “booms”, “zaps”, etc.) without deep knowledge of audio signal processing. It offers an interactive GUI through which you can tweak many parameters (oscillators, envelopes, filters, etc.) to sculpt custom sound effects; you can preview in real time, export, and iterate. The project includes libraries, HTML templates, and both ActionScript and JavaScript code. It has been well-received (over a thousand stars), but as of 2025, it has been superseded by a newer version called bfxr2, which is a JavaScript reworking of the original. -

Alternativa3D
Alternativa3D Flash GPU accelerated 3D engine
Alternativa3D is a high-tech, open-source 3D engine built for ActionScript 3 and Adobe AIR, offering GPU-accelerated performance for browser-based games and applications, with a focus on high performance and resource efficiency. Alternativa3D is a high-tech and high-performance 3D engine for ActionScript 3 and Adobe AIR. It supports hardware acceleration for browser-based games and applications. Initially, the engine was designed to meet our own needs but we realized that it wouldn't be fair to limit the use of the technology to just one game. That is why we decided to make it an open source engine. Since our top priorities are high performance and resource efficiency, we recommend using it for games with high-resolution graphics. -

mapgen2
Map generator for games
mapgen2 is a procedural map / island generator intended for games. It focuses on generating continent/island style maps (coastlines, mountains, rivers, etc.) with a vector / polygonal structure rather than a full high-resolution tile grid. Originally written in ActionScript, this tool emphasizes generating aesthetically pleasing island maps with realistic natural features while keeping computational complexity manageable. It supports exporting to SWF (Flash) via appropriate tooling. The most important features I want are nice island/continent coastlines, mountains, and rivers. Non-goals include impassable areas (except for the ocean), maze-like structures, or realistic height maps. -

Super Smash FLash 2
Super Smash Flash 2 is the most must-play battle game with 28 classic
SSF2 Fan Club: https://www.facebook.com/SuperSmashFlash2FC/ Play SSF2 Online: https://www.freegames66.com/fighting/super-smash-flash-2/ Nice news for those who love Super Smash Flash game, the upgraded version is better and better with an extra 3 playable characters to swell the ranks too (Marth, Zero Suit Samus and Chibi-Robo). Super Smash Flash 2's gameplay is very similar to the official Super Smash Bros. However, the most interesting feature of SSF2 is that character's health is measured by a damage percentage counter. It means a character is attacked, the damage will be accumulated, and percent value gets high. The controls of Super Smash Flash 2 are also different from the previous version. Make use of WASD keys to move Player while the arrow keys are used to control second player. The O and P keys still remain in P-1's possession, the P key for standard attacks, the I key for shield, and the 1 key for taunting. -
