I think your generation is placing tiles on top of other tiles. I keep running into places where i can't go and the tiles there glitch between different tiles but whatever on top isnt being recognized by the raycast as like a valid path
Yes, this is exactly what is happening, and I am in the process of finding out why. It worked as intended in the editor, but I may need to build it as a download instead of embedding in the browser in order for this bug to squash. Thank you for giving it a try though! I'm sorry it got stuck :(
