Hi - very sorry I didn't see this post. I didn't get a notification for some reason.
That's a very odd looking bug! Have you tried it in fullscreen, at native resolution?
I've realised that the recommended system specs were missing from the itch store page, so I've added them now. I'm guessing that maybe your laptop might not be able to run it.
If you paid for the game feel free to request a refund.
