Thanks for the feedback, we've seen another person not realize they should go upwards too so I think your suggestion is great.
Yeah our interpretation of the 'Dungeon' theme was different from most of the others but we wanted to do something other than your standard rogue-like. We found dungeon to be more of a setting and set it in a prison/keep of a castle environment which then worked well with princesses (not my choice I swear).
Glad you got some fun out of it and thanks again for the criticism. I look forward to checking out yours :D
