The gravity beam/fish physics are implemented really well. Very satisfying to suck up fish and plop them down. Coin collecting is also really satisfying. But it kinda ends being like a sandbox for that mechanic. I would have liked either some way that I could lose so that I could go for a high score or some goal to work towards so that I could go for that. That's my only note though, this is implemented really well and is quite fun to play even without something to shoot for.
