Just played it for about 30 minutes. Reading the messages is mildly fun. They range from amateur attempts to contribute to the game story (on june 12th, there were 5 of us...) to corny aphorisms ("i didn't I hurt her"), to hilarious attempts to derail game understanding ("physics affects THE DRONES") ("don't trust your boat").
It may be intentional, but the actual game itself felt buggy and it was difficult for me to interact with it. The screen would invert sometimes (I guess to swap between night/day), if I was off-boat during a screen change, buggy shit could happen, it's a bit awkward to paddle your boat.
I really like things that let you cast anonymous messages into the dark, so that's fun. But the game itself bored me within the first arbitrary loss of my boat. No idea why that happened, didn't feel like slowly paddling across screens again to reupgrade for another 30 minutes, only to "die" without knowing why.
