One of the best game in this jam I've played so far.
You know what you're doing, the FTUE is well balanced, you know how to introduce mechanics and how to gradually scale difficulty. And for me, FTUE on a Game Jam is key.
Added to that, your idea is original but your application of that idea is perfectly handled. Anyone can have a good idea, 5% of the work is getting the idea, 95% is the application of that idea. You nailed it.
Congrats!
