Loved the whole creative vision behind this game! The art style is so good, as was the music and the sound effects. I would definitely say add checkpoint to the levels, I felt like I got lost a LOT and dying felt real bad when I was far from the portal.
I also had some issues with wall jumping, it just felt clunky for some reason, maybe I'm just bad, but it didn't work a lot when I thought it should.
Y'all did great, very fun game! (if frustrating at times with the difficulty)
