This will be my first Ludum Dare. I have entered three 48 hour game jams recently (the weekly Fight Magic Run competition), and won one of them,\u00a0 so I’m pretty wamed up. I’ve been using createjs. The only base code that I will use that I wrote myself will probably be my key input class. I wrote it some time ago and it’s\u00a0 pretty messy but it’s worked pretty well. So I thought I had better declare it. Also my loading bar class which was written last minute and rubbish, but again it does the job.\u00a0 I don’t have a github, so I’m pasting the code below. You can use it if you like, but I doubt you will want to! haha
