This was super fun, the levels and music was a really nice vibe! Even thought the platforming can be a little clunky, what you have here is very strong.
The water mechanic feels good, id say its a big improvement from the original Hypnagogia with the secret water level in that game. being that it had a floaty feel, this game feels a lot smoother and intuitive!
The only minor thing that I noticed on my playthrough is a minor grammar error.
really looking forward to the full game when its finish! take your time, make it nice.
