This game is incredible for the time put in! I like me some Terraria so the game was mostly up my street. The visuals, lighting and sound were especially good.
Only real thoughts I got are it's pretty easy to get lost in the labyrinthine abyss, plus it's occasionally tricky to tell what you can break and what you can't at a glance.
The traps didn't feel too useful, felt like I could get away with just using throwing spears.
Likewise, as food heals you (which I like, btw) it does make Bandages feel a bit redundant. Especially with how plentiful food is in the sea.
I feel like mouse-wheel should change the active slot on the hotbar. Just something I've some to expect from games like this, heh.
Perhaps consider adding a button like in Terraria where pressing it consumes anything edible in your inventory? So a button for using any healing item you have, a button for using any food item you have and a button for drinking any fluids you have. Play a tone to let ou know that the attempt failed because you dont have any items for that task or something. This would free up the hotbar for weaponry.
