So far I love it! Great graphics and sound. I died on floor two but that’s the way dungeons go. Maybe you could add something where it tells me what a spell does when I hover over it?
So far you can check each rune in the spell building menu (there should be a popup text when rune is selected). But I am guessing you mean on the main dungeon screen ? Have to think about it (esp. that hovering on mobile won't be straightforward ;)
