I love puzzles so it was cool to see a puzzle game. Like others have said, I wasn't able to press space bar quite a few times and had t o close the game and reopen it to keep playing. At least it keep the level you're on! That was helpful to not have to start over. The puzzles got increasingly more challenging which is a great way to get people to play longer and keep their interest. Amazing that you planned out the puzzles!!! Good job!
