Hey! I saw your game on reddit and decided to give it a try, for being a prototype the idea is interesting and I'm curious on how it will evolve, I like the atypical inventory and crafting but as for now it is very not intuitive, but I mean, it's just a prototype.
Anyway I saw that you are already conscious of the paddling bug (which is very easy to meet) but I also found out that when crafting a spear with a rope so to craft the throw able spear it will sometimes just create a rope (which you could use to make the inventory) basically destroying the spear, from what I saw it happen when you first select the spear and then the rope when combining, but I'm not sure.
Last but not least I even managed to crash the game while crafting the spear, I don't know what happened and I haven't been able to do it again, I don't even know if the spear has something to do with it or it's a coincidence, but I'll leave the report here for you
