Thanks for all the kind feedback! I'm not going to lie - half the fun of making this game was doing all the goofy transitions.
We basically cranked out all the levels at the last minute - it was actually pretty easy once the core mechanics were working on our practice level.
You're totally right about the "R" key. I threw it in at the last minute, and didn't think very much about what key I put it on. I was like "R = Reset. Perfect".
