This must be one of my favorite entries! I love the fact you put a menu that is a level and a tutorial into it, letting the player learn in an organic way. I also enjoyed a lot the mechanics and how they fit the level design; the fact you can take multiple paths and choose whether to get or not to get the coins, while still considering you have be really fast to avoid the lava, adds a sweet layer of challenge.
I think the only personal nitpick I have is that E felt really bad and unnatural as a keybind for the powerups (when using WASD to move), specially when dashing to the right. I had to use my other hand on the E to play properly in that scenario, in which case I'd just rather have it as J or something close to that (and Z for people moving with the arrows). But that's all easily changeable.
Overall, great game!
