Snake + Sokoban
I thought I'd try it, because why not? Used Haxe and Sos' allegro.js (http://allegrojs.net). Music by Robson Cozendey (www.cozendey.com).
Controls are WASD or Arrow keys for movement, ESC for Level Selection, R for Restart, and M for Music Toggle.
Only 10 levels for now. It was 8 levels before - and I added a new level between 6 and 7, so there's a new level 7!
[edit] Has 12 levels now. I call it a day. [/edit]
