An undeniable classic. The art and animation, just like in Dad 'n Me, is absolutely beautiful. Probably the most entertaining part of the game are all the different enemy death animations. Seriously, there's so much variety. There's headshots, crotch shots, body shots, close-distance slices, splitting bullet shots, fire shots, freak attacks. And they're ALL really well animated. The freak attacks are really good for taking a breather, and I like how they remove bullets underneath you. The backgrounds are really cool too, and the way tou can jump around on them is unique, considering their style. Sometimes the edge detection is stupid, like when you're trying to get the 1UP. It's really annoying because you end up falling off the building and it's hard to judge where the edge is. It's hard enough with the helicopters, which, by the way, are OP, since they can shoot in, like, 8 directions, take a few hits to destroy, and respawn. The game is really difficult, and it's fair for the most part, aside from some things I've already mentioned, and some other things. The bosses are kinda underwhelming, and the final boss isn't entirely fair. There's no invincibility frames when he punches you away, so you can get hit the moment you get up, before you get the chance to jump. Also, the enemies can pretty much instantly shoot you if you're above them on a short byuilding.Also, I managed to cheat him somehow, by firing a bunch of bullets at him in the first phase without him punching me. The second boss is the easiest. It literally stops and waits for you to destroy it. The grenade guy is annoying for 1 simple reason. You can't get past their barricades without jumping on them or doing a freak attack, and the enemies have a habit of standing on the other side until you jump and somehow lure them. Overall, it's a cool game with great death animations and lots of difficulty, mostly fair but some not so much.
