Magic Hexagon

 As can be gathered from the game's announcement on Tumblr, Magic Hexagon is basically an open source clone of Super Hexagon with pony cutie marks, placing it under the "barely pony related" category. There's not really much to offer for feedback here without either essentially reviewing the original or commenting on the developer's taste in libraries/programming languages, although it would be nice to have some more variety when it comes to songs (the creator is looking for a musician though, so that might be resolved in the near future), along with pre-compiled OS X and Linux binaries in the near future.

 In case you're interested in contributing to the project or compiling it yourself, you can check out Magic Hexagon's GitHub repo at https://github.com/meh2481/magichexagon.
