Thank you for playing and giving such great feedback! Its very helpful to have a detailed list with things to improve on, I will look into everything mentioned. :)
Yes lots of things are like that because of the limited time of the jam. For example I didn't really put much time into the items, thats why they have no or bad collision and may fall through walls and also have placeholder models at times. But I am glad you still liked it. I will also write a bit of a devlog, though I don't think anybody reads this. :D
