TMNT seems to act randomly when using the second bomb in Game 2. It sometimes freezes right away, sometimes beeps weirdly and allows to continue until the next item is grabbed, then hangs. Also, I'm pretty sure there's something wrong with the air meter.

Awesome work on those graphics and on making these work, by the way.
