another good idea is to add a riddle to each room and a clue to each room

make it like a dungeon where they are trapped trying to escape

there are clues everywhere that are related to the riddles

doing a certain action might cause you to discover a clue

the clue can help you find weapons and new skills and also help solve the riddle

there will be like 20 small riddles that when solved get you a skill or weapon

the answers to like 5 will create a clue to a major riddle and there re 4 major riddles

the 4 major riddles will give you a clue on how to get out
