Hmm, that's weird, we've never experienced it before, and we even tested it on the steamdeck. What specs does your PC have?
13th Gen I9 13900kf
GTX 4070-ti
32gb of DDR5 ram
Motherboard Z790
a 1tb nvme ssd and a 3tb hdd
So not weak specs its the only itch.io game I've ran into that's given me that issue.
That's weird, do you use windows 10 or 11? We have a discord, if you'd like, you could ping us there and we could try to see what the problem is!
