Good game so far, I managed to almost make it to the 2nd boat, but for some reason the game started lagging really badly when i ran out of energy in that area.
Very good atmosphere! I enjoyed it. Add a few different hazard types, and it'll really stand out.
The boat speed did feel a tad slow, but hey... it's a boat. so I understand that one.
Honestly, add a fishing mini game, a few randomly generated islands, and some QoL, and you got yourself a full fledged adventure/survival game!
