I managed to reach 137 seconds, and I must say that I had fun playing this! The idea is well implemented and the graphics and sound managed to sell the effect nicely.

I liked the concept! I did 78.425s.

Really good game. Ambient sound instead of music adds a lot to the experience.

Nice game, loved the atmosphere! The theme was there, but could be incorporated a bit more. The only other thing is that you could spam the echolocation without any punishment, maybe the big fish could become aware of your position when used.

Innovative use of one-button with echolocation. Effective graphics and audio. Good experience for a short jam game. 

Only downside - I couldn't really see the theme "Two Colors" in the game, other than having different color fish. Maybe it could have incorporated the colors into echolocation somehow.
