The idea is very nice, sadly, it is quite poorly optimized :(
Tried playing and the game got stuck (I could press buttons, but nothing was happening) in the options. After restart managed to make it work, but got stuck again on a piece of terrain. Also, noone mentioned it, but the boat you spawn in is shaking the player wildly.
The idea is lovely and the visuals look nice! Hope to see this project in a better shape in the future: :)
