Features:* FrozenIpaq's original idea for puzzle mode and how to move squarez.* JimShoe's idea of moving the player using d-pad only.* Yet I added the ability to move them more than once, yet all examples are move once only.See my examples in the levels folder for how to make levels.Features:* in-game editor* new background graphicsChanges:* smaller grid, 23x12* can no longer exit game with START, must use HOME for now. just exited by accident too much when making levels* when reaching a level with no file, an error is no longer generated. Instead a blank grid is displayed. You can now use the editor to create a level and save it. All levels are saved using the level # displayed on the screen.Fixes:* Bug where you couldn't push blocks left at the top of the screen.
