I really enjoyed the music for this game, that and the pixel art complimented each other really well. The controls were a little hard to master at times but it was still decently fun to play the game. The main but of constructive criticism I'd give is to have had some upgrades that felt a little more impactful to the world other than just double jump and crouch slide, kinda in the style of jetpack joyride. But regardless of that, I still had a decent bit of fun playing this!
I do agree with Dominic about it being a bit hard to tell what areas were able to be collided with and which ones weren't but considering you did every aspect yourself, it's still incredible what you managed to accomplish!! It was a really solid entry :)
