The only problem was the out of control frame rate. I was getting ~2,000fps. That's nuts. There seems to be no options to limit the frame rate or enable vsync anywhere.

So my suggestion is to skip the native version and install the windows version. Then set the launch options to:
DXVK_FRAME_RATE=60 %command%

Then the game will run just fine without melting your GPU.

Other than that, it's great. A cool and stylistic game.

Also: Angler fish that have a light on their head are female. The males are tiny and don't have a light. Billy should have been female.
