Pretty cool aesthetics and solid gameplay.
Sliding felt nice, I just wish it was used more in your favour and not something you need to fight against.
Level 4 "was rigged from the start"
Nice choice of music!
The jump sound was not pleasant to keep hearing over and over.(I would suggest using a softer sound and an AudiostreamRandomizer with Random Pitch variation)
Overall cute, little game that becomes challenging at the end!
