P.S.: I also wanted to suggest adding a timer that displays both the opponent's remaining time and your own during their turn (it might not be necessary, but just in case).
Guys, another question has arisen.
I recently played Might & Magic VI with no one-way portals and encountered a non-functional portal. I mean, a two-way monolith, but I can't enter it. It's as if my hero from the other side is blocking it. Has anyone else encountered this? Or am I just hallucinating?
