Hey hey hey i just finished your game!
First of all, you are really good with game design. Introducing game mechanics and using them in next levels really got me engaged. I'm glad that you created different levels cuz it really paid off!
I think it would be a nice addition to press E to disable slowtime cuz sometimes I finished the puzzle but needed a platform jump which is not as precise as in real-time
Anyway really interesting game mechanic and good introducing to it in levels. I'm pretty sure you can carry this game on and release it one day!
