Cute game! Nice small scope. And major props for making all the assets! That's no small feat.
I never figured out where to get more charge? Maybe I was just missing something but it looked there just isn't anything to do that. The one other issue is that I wasn't able to actually press the "try again" or "quit" buttons at the end.
Some small improvements might be a crosshair or some other reticule in the center of the player view, make sure there are recharges available (or if they're already there, make them more obvious), and maybe some kind of warning when charge is getting low.
One thing I would beg you not to change is the vertical velocity boost when going up steps or from one seat to another. I don't think it was meant to work that way but that "feature" was a TON of fun. I kept trying to abuse that to see if I could get up and down the theater fast enough to get all 10 in one charge. Never managed to do it but it was so much fun to try.
