Great questions! Originally, the answer to all of them would have been YES, but I think the best answer is, 'If you think it’s fun.' The idea behind Devil Must Die! was to keep things minimalist, without needing a map or anything like that. Honestly, I wasn’t super happy with how the part about finding the stairs and new rooms turned out. I’m testing a few ways to make that better, as well as improving the loot on each floor.
I’m open to any suggestions :)
Personally I'm not a huge fan of the roll for exits mechanic as that makes my little goblin brain think it NEEDS to make a map. Personally I would rather not have to make a map, especially for a game i can (and currently do) fit in my wallet. Though I really like the idea of passing a monster as that offers more choice. My first thought is that you can pass a monster before you figure out what it is. But after you roll to see what the monster is, you have to fight. Maybe you can skip a monster but at the risk of the next one being stronger? Perhaps the path to the next floor unlocks after you defeat a boss?
