No they ain’t behaving oddly. Just find em annoying considering how long their hitbox lasts and how much of a nuisance they can be when you know where to go to end phase 1 the quickest, but they get in the way.
Also I’m not sure if it’s on just the zip version as I haven’t tried the others. The browser version doesn’t register my inputs well (it’s just an issue on my end and the browser I use, don’t worry), and the other version I can’t even get to work (because laziness on my end).
