This is a very nice strategy game. You need to reach the exit and collect keys and coins along the way. Each level got some essential elements missing and you need to fill them up.
Sometimes you need to place a block to cross a gap, or you must fend off an incoming spiked ball. It is up to you to find out what is needed to reach your goal. Reach the exit and collect as much coins as you can.
Use the [WASD] keys or the arrow keys to move. Use the mouse to place a certain block. If you want a different block than the one selected, left click it in the menu on the right.
