Nice point and click game! I really enjoyed the art, and the mechanics were very smooth. It was cool that every puzzle piece had its own separate SFX (or at least I think they did), it helped to differentiate what I was clicking on. I did wish it was easier to differentiate the interactables from the background objects like the corals though, because I found myself clicking on lots of things that didn't do anything. I think the excellent SFX implementation helped move me along when that had me stuck. I did also like how the puzzle pieces interacted with each other, it was like the whole aquarium was one big Rube Goldberg Machine. Great work!
