Are these lines supposed to be there?

Hey there thanks for posting! They're not, it may be because you're not running the game at a multiple of 640x360 (i.e. 720p or 1080p) which is the native res of the pixel art in the game. There's a setting in the video settings to lock the gameplay resolution to 640x360 that which might address things like that, though I don't think there should be too many other occurrences of artifacts like that so up to you. Might be able to take a look at it and come up with another solution at some point, thanks again! And sorry I didn't see this for a month haha.
