Thank you for trying it out and posting your comments! I'm really interested in learning about two things you posted on, so I can fix them:
1) How did you get the enemies stuck? Was there a certain set of steps you could do to cause that? I haven't seen that happen (at least not in the final game), but I'd really like to fix that.
2) for the volume - another person mentioned that, too. Is my default volume too high, so you had to lower your speaker volume, whereas other games didn't force you to do that?
