It doesn’t display all the buttons on my iPhone

This’d be a rock-solid adaptation of Orthanc, but the menus don’t display all of their buttons properly, rendering certain features unusable on iPhones. I don’t have an iPad, so I can’t comment on how well the game works on those devices.

Response from developer

Sorry about that. Should be fixed in a release soon.

Game over in less than a minute

Not sure what the point of this game is. I give it credit for the simple interface, it works well enough. But you make a character, go fight some monsters, and die within a few fights. Maybe that was fun in the 70’s I guess.

Really Fun!

Super fun, my dad played it when he was a kid, I see why he likes it. Definitely would recommend if you want a simple dungeon crawler!
