I love the concept it is very original and hard to control/predict what your laser can do. You end up killing a lot of people by accident and the character's personality is just perfect! One minor thing, you can exploit sticking to walls to hide your laser, but this also feels somewhat according to the theme and the character's personality. Maybe some smart Level design could get you to sometimes abandon your safe wall and force safe players to take risks and go from one wall to another. (Maybe glass walls? lol idk). Nice work!
