Great game, I had two issues 1 there was a bug where if I hold an item like box or the box cover I fly to the sky, 2 i didnt like that you need to walk to all the upgrade boxes would be helpful if i could teleport them to me or something like that.
I was also thinking about adding something to teleport the boxes but ended up not doing it just so that the player will have a reason to move. But yeah, I should consider adding that. Thank you for the amazing feedback
The problem of flying away can easily be fixed by editing the physics settings in the project settings. Uncheck the collision between the layer of the box and the player :)
