Nice spin on the theme and core mechanic has potential; however, had some technical/gameplay issues that really limited my enjoyment.
Firstly, I could never get very far. I found that the time between the fish appearing on screen and it catching you meant it always got me. Even if I hid under plants/arches/rocks it would just swim through them and get me. Wish I could ink it or camouflage or something.
Secondly, there was a bug where the game froze for a second or so when I picked up the second piece of trash.
