Thank you so much for playing! Technically the arrow keys should work for movement .. but the alphanumerical keys for abilities/objects are fixed. Maybe qwertz or azerty could work but dvorak or more exotic layouts could be difficult :D
I have an azerty keyboard, the "q" is where "a" would be for you so I kept putting torches everywhere (while think of moving leftwards) and blocking my own ladder ways :) I'll give it another shot with arrows
