Enjoyed the game much!
The puzzles were simply well thought out, and uh, was all the art assets really custom-made for this Game? That's impressive!
What I would have liked is faster movement: Suika kinda lingers for like a half a second or so too long everytime she moves. I think this movement "endlag"(?) is unnecessary and can sap a bit of patience when the player resets the puzzle.
I included this game in my showcase of this Jam, here:
