This was a really cool take! Nice work.

I really enjoy the concept of controlling the speed of the things around you! It makes for really cool mechanics. That said, some jumps where I needed to control the platforms to get over holes were really hard to get through.

This mountain is so cute c:

The idea that the game brings is so euphoric, really, and the music changing accordingly to the set speed is so nice! The moving platforms killed me (a lot) when I first started, I couldn't get the timing correctly and it was one of the downsides for me: as the game goes it gets a little chaotic, you have to managed too much variables with so little time and mechanics to control (being able to move left and right would help to complete the core mechanic), but you do get used to it.
Amazing work!
