For a game developed in 24 hours, I enjoyed this. From my experience, I think that this game has been one of the better games made in 24 hours. I really wouldn't change much about this game if I had the chance to.
Maybe make a forum or something where players can suggest items? I'm getting tired of just seeing suggestions for items in the top comments. If there already is one, then maybe redirect the players to them?
Please, can you make it able to level a group of people at a time? One of my raiders is level 1000, and i want to level everyone else up EXCEPT him. He saps up all the experience.
There's a thread on the forums, but ideas are welcome in the comments just as well. I do read them all.
