I was not expecting a Geometry Dash section, what an uplifting gameplay, took me a bit to get past that and I beat the game.
The game showed all sighs of known issues, but I wonder were there some Linear Interpolation(lerp) attempts, the jitter made it a bit difficult for jump boosts and flinging. The platforms didn't have labels or rails to inform the exact move limits, but I could move them around a bit and found out.
Overall, very interesting design choices. Very nice art. I like the character design and dithering art-style.
