Exploration tip for new adventurers
It's more efficient (saves food) to map out larger rooms in a zig zag pattern...of course you don't necessarily know how large the room is until you explore some of it
What I call the 2 finger shuffle...because I place 2 fingers on the screen to do my exploring.
Hug a wall and move vertically diagonally away from it them move diagoanlly back toward the wall, repeat until you hit a corner, switch to horizontal diagonals.
Basically using a W movement pattern (or M if you're at the top of the room)
Sometimes chucking something down a room will reveal things on the mini-map as the projectile goes by. The down side is you might wake something up by hitting it
