Love the theme and cute fish! I'd say the art is very good and the story is hilarious. I like the minigames too, especially the PC one. The game overall is quite well made and I like it quite much!
For some criticism, I'd say firstly that there should be a timer somewhere on the screen, just to add a bit of urgency and tension. The game also has quite some downtime in the form of moving around the scene. I get that running around is part of the gameplay too, but I would rather spend more time frantically going from minigames to minigames. Going from valve to button 3 times in a row is quite frustrating.
But anyway, this is a very nice game indeed! Nice work!
