Amazing game. You can play and review my game as well if you like.

The environment is built so well making swimming around super fun. The fish movement and the underwater effect really sells it for me. Also flopping up the stairs is ridiculous XD

Fun concept! I'm impressed with how fleshed out the environment is, and that I didn't encounter any Z-fighting or wonky colliders while playing. Leaving the water and slowly flopping up the stairs was the highlight for me. That said, I ran into some problems. My first issue took place near the beginning when I swam down through the grating and into a pipe. The current pulled me against the wall next to the pipe entrance and I had some trouble getting through. After that, it was pretty smooth sailing until I grew so large that the camera clipped inside the salmon, making it impossible to see exactly where I was. I started the game over and avoided the orbs to prevent camera issues, and I reached a plugged pipe with some kind of needle sticking out of it. After struggling for a while, I ended up giving up without finishing the game. I hope you continue developing Salmon Go because I'd love to see how it comes along with some extra time for polish!
