Sweet !
I loved the vibes that reminded me old flash / ps1 games.
The music was quite repetitive but also very pleasant
I agree with Lerg Bwo, walking a bit faster, gaining some speed with ice or have an increased fall speed could make it even more enjoyable.
Maybe you could work a bit on the fluidity of movement, and the readability of the platforms that you can reach, which isn't always perfectly clear.
Otherwise good job :)
