Really cool idea with lots of potential! I really like the aesthetic of the game, visuals and sound-wise very appealing and nicely done.
The few first few levels introduced controls and core mechanics precise and easy to understand, that's always a plus.
Only thing I wished is that there were more elements than walls and spikes to work with for, but I completely understand that time is limited, especially during a gamejam.
For the short amount of time however, your game and what is has to offer is amazingly polished! Great job!
