Oh the cause of him getting stuck was actually the opening that I haven't closed up during that. I closed it though so he shouldn't be getting stuck anymore. but shouldn't him as well as the others go left instead of right at the start?No, I just mean it's showing he took the downward path; 90's not an available option because he can't move backwards.
All that matters is that readout shows all the ghosts should be working fine -- they're detecting paths and supposedly taking them. It also shows Blinky getting stuck somewhere for some reason.
If you want, upload a .YYZ of your project to some file hosting site and I can take a look at it, because everything's working fine on my end.
