Really cool game :D
The art style was lovely and I did like the voice overs (even though they became repetitive after a while). While I know this was the point of the theme, but restarting at the very beginning for making any mistake became quickly annoying, especially because there wasn't anything new to do except walk. The new mechanics could've make it faster, but it was usually a just walk back. I would suggest making the way back faster and/or have more things. Also it was unclear when the dash recharged, leading to a death.
Something else that I liked was how quickly you introduced mechanics, as that kept many of the rooms unique and recognizable, and wasn't confusing due to how they were straightforward.
Good luck in the jam!
