Very conceptual & atmospheric, I liked the game! The controls are a bit tough, though - it isn’t explained (in the “controls” section inside the game) what are the [Q] and [E] keys for, and the [R] button isn’t mentioned at all. I liked the boat movement, though it didn’t seem like accounting for the wind direction? Also the compass didn’t work for me while on boat, it just stayed frozen & not rotating.
Nonetheless, great job! I’d definitely try a full game like this.
(btw, try & rate my game if you like shooters)
