This looks amazing, I'm particularly impressed by the quantity and quality of your levels.
There were a couple of difficulty spikes. I had to go back to level 4 after figuring out the splitting mechanic in the following level for example.
You take this mechanic a lot further than I would have expected possible in a game jam.
I also liked the bonus challenges in each level it makes the games feel above and beyond.
Impressive work and well polished!
