Oh I see, something with that shader must be causing problems then.. I'm not super sure what's causing it exactly so I just disabled it xD Since it's just a small wavy effect the game should work fine without it.
I uploaded the version where it's disabled here: https://drive.google.com/file/d/19-gWMiWHCdbkIyblFWclrntyBwamHJ4N/view?usp=shari...
Hope that fixes it!
