Lots to like here, from the pixel art and the prof character to the concepts of the gameplay. I completely missed that you're supposed to collect specific things, so I collected everything at least twice before realizing that you're only supposed to get what it tells you in the top left. I got a few more after that but it felt endless at that point (after about 4 eels and 4 angler fish). Not sure if there's an ending or not. Would be cool to see more, especially with more unique behaviors (maybe even dangers/attacks) for each fish. unique sounds per fish, etc. Great project overall, nice work!
