Hello. Yeah, I thought that puzzle was easy enough so I didn't leave any clues. That was a mistake. I'll probably release an update for the demo with some fixes.
The puzzle solution:
3 1
2 4
Thanks for playing the demo!
I have played the Demo and it was great with the puzzles and secrets (don't know if I found all ;) ) so now I'm waiting eagerly for the full version. But I have still a question. Will it be possible later in the full version, to recover in the garrison, i.e. to heal without healing potions, like in a inn?
