Some nice elements to this for sure! I quite dig the art-direction, I think the foreground and player don't feel entirely cohesive with the background and could be tied together a bit more, but the jagged minimal abstraction of the levels is cool and the colours create a great vibe.
I didn't finish the game because the controls felt a bit janky to me and the platforms felt unfair at times. There were also a few points where I felt like I had to jump blind and just hope I'll get to a platform, which doesn't make me feel in control as much as a player. Music was nice, wish it wouldn't restart every-time I died though. The quick respawn is appreciated!
Start screen is lovely and I like the chapter illustrations as well.
