1. I couldn't get to secret room 29 from secret room 28. I tried going right, left, up, down... couldn't find it.
2. After defeating the dragon, I tried to do some of the side quest. I took the sister back to the witch Imogene, but she didn't give me the map to the library, no matter how many times I left & re-entered the swamp after delivering her sister. If I don't have the map, I can't do the rest of the quests.

This game is the worst of the three.
