I spent the first few minutes trying to complete the levels with JUST the dash, and getting stuck haha. Then I realised I could jump too, oops lol. Really like the art style - for a moment I thought it wasn't 64x64! It gives the impression of being higher resolution (probably because of the open spaces so the screen isn't too busy).
Trying to solve the levels with the jump/dash combination was good fun. I even managed to pull off some (if I do say so myself) cool moves and solve the puzzle in a different way to what was probably intended. The wall jumps felt nice as well.
Oh and the music is great!
Good job!
