I reaaaally liked this one for a couple of reasons.
1. The gameplay is nice and predictable in a good way. One issue is that it can be pretty confusing initially, until you get the hang of the mechanics.
2. The visuals are great. Same goes for the sound.
3. The little details, like the floating particles and the crisp movement make it shine.
Also, I really agree with your choice for playable level selector, very old school.
Good luck in the Jam!
