Thanks for the feedback!
I completely forgot to provide controls lol but I've added them to the description now. If I continue working on the game I'll definitely keep your suggestions in mind :)
While I have not personally come across the glitch you mentioned, there is a chance it could be real for everyone as I did not have very much time to play test during the 4 week challenge.
And yes there is an item spawn cap, but discarded weapons don't count towards it - I might make discarded weapons destroy themselves in the future to stop the arena from filling up with useless items.
Thanks for playing, and I hope you enjoyed it :)
