The idea is this: Using Tetris-like blocks, fill in a square. To move the pieces around, use the joystick and to place one, use fire. To start over again, press the reset switch.

Release notes:

New version with title screen and timer that goes up to 60 minutes. Also added you can’t place the pieces on top of other ones. I’ll be making more puzzles like the first one in the future
