This is a ti basic game similar to escape (one of the axe contest programs), which the object of the game is to escape from one prison cell to another, by beating the puzzles found in that room. You can move the big N blocks, and the black = blocks are solid/stationary, and you can push the N blocks into 0 blocks (holes) to fill the holes up. Notice these are the easiest levels (don't want to give solutions away), and so far I only have the first 10 levels with more to come in the upcoming week. It gets pretty challenging.
