Ooo, this concept was super fun! I loved the use of the theme, and the rotating level mechanic made for some really clever puzzles. The character art is great too! really nice 2D work, especially for something made in just 5 days!
Some levels felt a bit easy to cheese, though. A few times I could just launch the capsule straight to the goal and die once to progress. It’d be cool to see some levels where the goal is harder to reach or needs to be unlocked by solving something first.
I also ran into a few UI bugs and crashes, for example, pausing after dying caused some weird issues, and when I hit skip level too many times, the game froze completely. I could move the character with the mouse but couldn’t control or pause, so I had to refresh the page. 
(stuck :( )
Overall, this is an amazing game! It’s full of charm, personality, and potential. I really hope your team keeps working on it!!! I’d love to see a full version someday!
