I couldn't stop laughing with the screams of despair lol This is a really cool idea, I love how well the Slow Time mechanic works in here. The only tiny issue I had was that the brush's hitbox was a bit too small and it was difficult to paint. It was made way easier with slow time.
The pixel art is wonderful, and I specially liked how you handled the parallax effect in here, great job! All the extra stuff you can check in the lexicon is also a great detail, and shows the potential of expansion in the game. Great job in general!
