I have heard the start of this song so often it is burned into my brain.
The walljump feels great but only when it actually triggers. When you are to close to a wall it just doesn't which is a problem since the levels death barrier moves so god damn fast that a single mistake instantly kills you.
I like that it is synced to a good song but just slow it the gameplay down a bit. It can get frustrating really fast.
With some slight tweaks to the dash and speed this would a really good vibe/game. Especiall with that awesome story setup you did at the start.
