First of all, thanks so much for playing my first game!
If your game becomes frozen on the level select screen, I added a button in the Pause Menu that will fix it! It forces the game to let you play the quick 1st level again, and then you are unstuck :D. I can't quite figure out what causes it to happen, but seems to have something to do with the final boss level on some computers. I hope this fixes the issue! I have gotten a few messages of people 100%ing the game, that's so awesome!! :3
Thanks again - Neat Games.
