At first glance the concept seems simple, but it ends up being pretty fun if you give it a chance! I wish there were more levels - I felt like it was building up. I was surprised when I got to the bonus level and saw it was the last level. I wonder - were you working on more levels and just didn't get time to finish them?
I tried a lot on the bonus level but I gave up eventually. Other than that I don't have much feedback - I actually really enjoyed this game.
I think we have similar concepts, so I would love your rating / comments on my game as well, to see what I can improve too.
