I was sure I played it before aswell. So its been pretty confusing. I'll see if its maybe something on my end. Did you use any Engine or Framework for this?

It's gamemaker, only thing I can think of maybe try it with itch.io app and see how that one works at the moment.
Also I'm aware of the portal bug if you get to play, screen goes dark unless you dash into it but if you move out of the portal it gets normal again. I fixed that and changed some little stuff but waiting for more to upload it again.
