Boat mechanics are some what decent (felt nice for the first 5 minutes, then it kinda felt like the ship was half sinking).
It was almost impossible to kill some creatures as they spawned way too close to you and approached you way too fast.
Also i found a bug where the creatures would path-find to you ignoring land and going on top of it.
Overall the game could have some potential if the base idea would be developed further.
Have a great day!
