Thank you very much! Yes both issues you mention are things that I would have changed had I forseen certain overall problems. Like the killed going off screen thing was just better than the bugs I was having with collisions when keeping them on (they essentially didn't die, but couldn't catch up). And the length of levels 2 and 3 is far too long. I think given this insight on completion of the game I may have done smaller levels, where you have a normal level or two, then a boss level. If I update the game these will definitely be changes included!
