Nice little game.
It has a very relaxing/tranquil feel with the music and slowness of pace even though you are meant to be shipwrecked lol! So it just felt like more like a laidback exploration of the ocean... That is fine i like games like that the Globetrotter one in his jam for example.
As someone else mentioned below though it was a nice 15 min experience. Once i got the motor and everything became a lot easier i almost didn't feel like firing the flare to be rescued.
Thanks!
