Short, sweet, effective!
Making a puzzle game is hard. Making a puzzle game for a jam is even harder. Yet, you guys have pulled it off - massive kudos! The game doesn't trip over its systems, puzzles are logical and engaging (although I will grant that they are simple - but it's a good thing for a jam entry!), the art style is striking (yes, I know, Kenney assets, but you still gotta set up lighting and select the right stuff!) - you can definitely grow this concept into something bigger and put it out on a store.
Now, for critique... The movement felt a fair bit "stiff", I think I once noticed a lack of coyotee time (if it's present - it's a bit harsh for a game that's not about mastering jumping between platforms), and the spinning carousel of abilities/effects was a touch distracting. Liked the left side panel with them though, that was really well done!
Congrats on your jam entry :)
