I think the game is going in a good direction, quite a shame that it'll be released without fanfare at some point in the future, but I'm happy with the mechanics and how it plays. I've modified the light gun a bit because it wasn't fun enough to use and I've started working against unity 5.3 on some UI/code things, but things are progressing! I've created two new rooms day as well.
