Thank you for the kind words.
Agree on the checkpoints and difficulty curve being off. Ran out of time getting everything finished. I'll fix that up after the judging when I can update.
Space was the next level key but it kept throwing the dot at the start of the next level which was bugging me. Changing the key was a last minute "fix" that was really more of a "don't look at the problem right now" LOL.
