Thank you for commenting! :]
At one point we were thinking about an item drop mechanic, so you could throw stuff on the floor and pick them up later, but we scrapped it. Part of it was due to time constraints, and other part was that we didn't want the game to be about pre-making weapons. It's all made to order! We'll still consider it in terms of the future of the game, though! :D
We'll definitely want to improve the movement mechanics/controls so that it's less straining on the hands! Sorry about that!
