Basically what happens is:
If you fix a bug (smash it with your stick) you fix it. Then it appears fixed on the bug list. If you die on that same level, this resets. If you played the browser version (or it seems like, even in the downloaded) you don't get the proper endings according to how many bugs you've fixed.
I am really thankful for your review, I really should have communicated its mechanics a little better, but I didn't quite have the time for that.
And, again, I'm really glad I could make a game that appealed to you. :)
