Thank you for all your feedback! I did incorporate a lot of while loops for the mystery box and the zombie spawning so there is a fair chance that is the cause to the crashes you've experienced. If anyone here would like to see updates to this, let me know! I really loved working on this project and wanted to put more time into it than I had. I definitely would love to add more weapons, fix bugs, and maybe even more maps if there's a demand for it! Let me know!
I will definitely try to fix the soft locks, as well as the zombies not attacking, but like I said reply to this if you want to see anything else done to it!
P.S. - For those of you that crashed when you died, there is supposed to be a Game Over! type screen that appears, but I believe I know what is causing the crash before it appears.
Thanks for playing!
