Awesome game, this was very fun! The graphics were great, I love the music and the responsiveness of the controls. The robots were the most difficult part of the game. I tried shooting them but wasn't able to deal damage? Aside from that, clicking the mouse repeatedly for about 6 minutes straight cramped my hand. All in all a great game, and I appreciated the use of checkpoints! If this ends up getting a mode without a checkpoint system, I'd like to try that too!
