Bug? Where (on Android) the game takes 30 seconds to 2 minutes for every turn passed. I'm in floor 5, and I've been using ice to get rid of the lava, but for some reason the game locks up every move/wait/attack i.e. every time a turn passes.
Note: it seems to happen when I affect the environment. Using plants, water to create steam, or temporary spells don't cause the issue. Tunnel and ice on lava do make it worse.
Edit: interestingly the problem goes away the further I get from where it started.
