I tried your game! I got all four keys and I tried opening the door at the top afterwards but it doesn't seem to work. I must admit that I am baffled at the puzzles included. The hedge maze was a bit irritating, especially with the high encounter rate. The portals took me a while and I was happy to find the answer in the book to speed it up. I hope I'm not sounding overly critical, but the inclusion of an Undertale based puzzle was baffling. Especially since you took the time to write in several books to summarize the plot. You can get infinite money from Gil, so I was able to stock up on as many items as I wanted. I do want to be clear and say that I think this game is okay for what it is, but it could definitely use some work. I hope you keep working at it and improve!
