Hey, thanks for playing the game!
Demo is pretty open-ended when talking about "finishing" it, legder hunt is basically added on top of existing "escape the mansion" quest. It can be finished in couple of ways too, but you have to have certain skill combination. There are three ways to get to the closed room, as well as three ways to free the bard, but in original idea escaping the mansion was the main goal and then you could replay it with better stats to unlock new ways to interact with the environment. Basically you managed to free the bard, so the main doors should be open, new ending could be played and you could start a new run with more points to distribute. Also which achievements have you unlocked (press 'i' to see them)?
Low intelligence is a hurdle but you can still free the bard and get the ledger with very low stats. Higher int helps though, with int 3 you already have the perception perk and Dirk knows more about certain items when examining.
You shouldn't be able to go down with the admiral when the bard is gone! Good find! I have to get rid of it. Which other events you managed to trigger that didn't make sense?
Mouse is a planned feature that is disabled for now. I want to have the option to play it completely with a mouse. Jump on the right click. Left click on the enemy and Dirk starts swinging. Most of the easier features like walking, talking and moving through the screens was already working but it's still undercooked so you only have a pointer now :P
Once again, thanks for the play and kind words. Will do my best to turn the game into a wild ride.
