I like Desktop Dungeons because it is a great rogue-like type of game to play when I don't have the will to play
ADOM/Nethack/Etc. But the mouse-only controls just kill me. Please please implement keyboard controls, at least for moving about. I know that mouse controls feel more modern but sometimes they can be a pain and to me they are immersion-breaking.
Spell casting could also have a keyboard component (target closest enemies, arrow keys to cycle). I'm not saying to get rid of mouse controls, just please let the keyboard be an option
Thank you for reading my feedback and keep up the good work
