Thanks for the feedback.
That is really weird. There have been close to 1000 D/L on this site alone for the game since Sunday and no comparable reports.
WASD was in the game as an alternative originally, but I commented it out because it screwed occasionally with renpy built in commands when keystrokes were buffered. If you have any background in editing game files, you could just uncomment wasd or change it to any keys of your liking. The code is in the file …minigame_dungeon.rpy (just search for „KEY“)
I will implement an alternative set of keys (maybe ijkl is a good idea) in the next release anyways.
