@Rook Sorry for being annoying about this, but when you go to try and start a duel (this is happening in the opening duel between yugi and Kaiba) Kaiba says "It's my turn" and it goes to match phase, but then does nothing.
The game still allows you to click and it takes your inputs, but you cannot click on anything to open it. You are still able to move the camera around, though.
This was tried on MacOS and iOS 17+, my bad on the long post just wanted to give the most info I could
EDIT: To add onto this I downloaded the version from the App Store to play it and see if there was something different. before they start the draw phase and say "IT's my turn" an objective pops up that is not shown in the hack download.
