da third game in the "Bullet Bill" series that kicks a lot of ass since you can break a bunch of blocks and destroy a shit ton of koopa kingdom/mushroom kingdom infantry. theres like a trillion characters and powerups you can mess around with too, as well as SECRETS and ACHIEVEMETNS so go crazy with that too lol

also there are a couple references to Psycosis91's older flash stuff like The Thwomps being playable which is so cool :D
