I was able to get through the initial "E to begin" screen by pressing it a second time, but going down the stairs it seems like the fade in/out doesn't trigger right. I'm able to walk back onto the stairs and get a flash of the next floor before it swipes over to the first one.
Seems these are all related and to do with the scene transitions, this is Chrome on macOS all extensions disabled, then Chrome Windows the same, Edge, and the exe.
Strange that it's only a handful of people! Holding off on rating as this actually seems like one of the better games from the little I've been able to do so far! LOVE the style you've got here.

Thanks for the positive feedback :) I am running Windows myself and don't have access to a macOS machine so I can't debug on that platform. I will upload a version without the transitions later so you can see if it fixes the issues you are having.
Edit: Just added another .exe without the transition animation.
