Using your face to catch on to the edges of platforms was great, and the only move left or right while jumping was very unique. It didn't feel like the theme interacted with the gameplay very much though. It was there in the environment, your character was the brush, and it's shape definitely had an impact on how you moved - but besides that, the theme/object where more there, you didn't interact with them as such. Nothing mechanically separated falling off the edge to a regular platformer, it didn't feel "overflow".
The graphics where interesting though, the background was trippy. I wonder how you could lean into a more psychedelic angle with this stuff.
