I decided to demo your game on linux and it seems to work fine. The ost is very nice thus far. the battle theme is very groovy as well, nice work! As far as UX stuff, I found it strange/uncomfortable use E for interacts in the overworld, maybe this should be rebound to spacebar. The ocean sprite you should redo that as a shader. Dying in combat and hitting continue softlocks you? don't make fun of me for dying, I did get to the end of the demo. nice game, keep it up
