I was working on a another game when after programming the enter first time script I tried running the game and it said error room -1 does not exist when the room im in is 1. What's the problem?
Check the "Starting room" property of your playable character in the Editor. It could have incorrect room set.
Also, make sure you haven't actually got a file named room-1.crm in your project folder, as I recall that causing problems.
