The library riddle was one I'd never heard before, I liked it a lot! There's a lot of key chasing. Needs persistent room states (when you get a key, leave, and come back, key shouldn't still be there)
Thanks, sadly the key chasing was just there to help me with some ideals for puzzlers (I even think I did to much for a short demo) and I may not have tested out the ;get a key, leave, and come back to see if it was still there.
