You're absolutely right about the beat one thing. I can only attribute that to tunnel vision. We wanted the character to get the first move on the first beat, implemented the systems, then just didn't realize we had the beats wrong until the game shipped. That'll happen.
We had a bunch of ideas for more things to do, more enemies, more pressure somehow. We were working on an enemy that fires a laser across a room, had all the art and everything, but the laser just refused to properly interact with anything so it needed to be cut. Maybe after some rest we'll come back and play with it some more. Some kind of forced movement, or a penalty for missing the beat might do a lot of good.
Thanks for playing, and for the kind words!
