omg you're so correct I was using display_get_width when it should've been display_get_gui_width AAAAAAAAAAAAAA THANK YOU SO MUCH For figuring out the issue! Sorry!!! I'm such idiot! Will get this fix out asap!
It's really no worries! Happens to the best of us haha.
Also just want to say I've played your other game Monster Girl's Labyrinth and became a fan, so happy to be a part of making your new game just that little bit better :P
Happy to help! Also if you're ever interested in a collab of some sorts (just spitballing, nothing in mind currently) let me know! I'll def keep an eye on your development tho :D
