I couldn’t really play the game. When it started, I didn’t see anything, unfortunately (same as the comments on the game by “ViciouslyViscous”).
I'm not sure why the black screen appears, but it's only in the initial cutscene, so you can still jump off the boat and skip the initial cutscene.
I was able to get it to work on my Windows computer using the downloaded exe. It's worth the download
