BEHOLD! One of the bestest games ever made (also free): ROCKS 'n' DIAMONDS!! You have to collect diamonds, but avoid rocks. Simple(?), but fun. There's also a level editor/creator. Most levels have puzzles and this game combines Boulder Dash, Emerald Mine, Supaplex and Sokoban. Attached are 33 of my best levels I made. Some are simple, some are eye candy, some are tedious, some are tricky and some seem downright impossible. But I assure you every single level has indeed been beaten once. Extract to the "levels" folder in the game directory (where the exe is). It would be a good idea to play some of the default levels and look at the element info screen before trying to beat my levels. Have "fun". MWUAHAHAHAHAHAHAHA.
