The main character and his friend really like a game. It's going into some closed beta virtual reality thing where they get a bracelet that lets them use magic. They have to travel to a castle off in the middle of no where that was constructed just for the game testing. MC ends up getting healing magic. There's a crazy glasses guy that manipulates metal(?) has a slight god complex. Pleeeeease help me figure out the name of this one. I read it a long time ago and I just can't remember the name..
