Mouse kept moving off to the other screen, need to confine the cursor. I wish there was a free mode that didn't end the level at just $10k.
I found the whole middle-mouse rotation thing really confusing, but I think it's just the tutorial being told mostly through text instead of just making you do the thing, so I figure it'll get better as you iterate on the tutorial. Everything's really satisfying, but the current levels are pretty much tech demos, so I'd like to see what else you can come up with in the level design in future.
Accelerating and dragging the bat horizontally across a table has got to be my favourite thing to do in this game. I want to see a fancy ultra-long dinner table with all sorts of plates and glasses on it just for this.
