Here is my own library that ill use for Ludum Dare #29 and ill release it to you guys aswell.
This is a game engine and its still in development so i dont have a wiki or anything but i release it now so you can play around in it, if this is used you must include credits in your game(the game startupscreen will be fine).
If you have any questions about the engine or want to help/join our team, contact me on email: flash13records@gmail.com or on skype: v7_flash

So here is a download: https://www.dropbox.com/s/vz771v6ab96l7b7/LostEngine_0_5_5_2.jar
