this is an excellent example of the perfect game jam [game]. fully functioning/playable and completely stand-alone enjoyable. the graphics are good, the controls are quick and very responsive, the guns sometimes are slightly glitchy but it really doesn't effect gameplay overall (although, not sure if this was a glitch but at one point i had a separate gun that was firing from the walls. it was incredible) most importantly however is how much potential this game has post-jam. you should definitely pursue this, it would be insane to make co-op possible. most of all great job, you should be very proud of your game
