I hope it’s okay to waste keys because I definitely wasted one ;_;
Spoiler:I teleported inside the lighthouse from the underworld but couldn't find a way out, then later opened the door to the lighthouse at the behest of an NPC but nothing changed and if I ever wanted to go there I could have just warped from the underworld like normal so I am just down a key
It's definitely okay to waste keys!! There's a room that will consistently spawn a key if you have none, so you'll never get screwed over for lack of them.
