This game gave me Cube Escape Collection vibes!!! I love these kinds of games (general puzzle/escape room esque). The style is really cute and I love the sudden switches between tones, be it Death's tone with their demands or the colours! Really fun. I also loved the JSE easter egg. I clicked that way too much XD
As for my one thing I hope for a more polished build, I think a cursor UI when you hover over something interactable can really change the feel of this game. A lot of the times I found myself clicking around everywhere to see if there would be any response until I would pick up items. Otherwise the story was cute (the fishy is saved!!) and I had a good time :) congrats on your game!!!
