I didn't get the controls at all in the beginning, because I timed pressing 'W' exactly with the enemies turning around, so I thought I would die if I press 'W'. Figured it out eventually though. Got to level 5, but that slope on the final boulder was tricky. Music and art are really good :) very well done. I'd recommend an intro screen akin to this (https://stuffedwombat.itch.io/stok), so people will know the controls even if they don't go to the actual game page ;)
