It saddens me that you're facing this issue! I suppose it's related to your computer: do you face those same issues with other games made with Game Maker Studio 2?
1. Wow thank you for a reply. :D
2. Actually no, i never had problems with other games made in Game MakeStudio 2, this is first one.
3. But don't you worry, despite on this inconvenient bug i still finished the game and i must say it is very clever to use knife and gun not as a weapon but as a tools, i never saw something like this other games. Anyway thank you for reply and good day to you sir. :D
