Omg the idea is so cool! I gasped when realized the key mechanic, love it super much.
The graphics, sounds, and the whole atmosphere are just amazingg
Only problem is that I figured out a way to cheese it after a couple of minutes :( If you wait till water runs to the left part of the screen you can just jump over it and run straight to the door, that works every time xd
Despite that, I had lots of fun playing, and if you are planning to continue working on it please reach me out, I would love to help by playtesting it
