Crash's beginning of the end.
Three years after The Wrath of Cortex, N. Cortex returns and plots vengeance against the bandicoot... except that two seemingly alien parakeets quickly come into the picture, and now Cortex, Crash, Aku-Aku and Uka-Uka must team up in order to stop this new threat. The script is easily the game's strongest asset, unlike the last game, the story is hilarious. Cortex is now a more exaggerated version of his previous self, and he steals the show(Partly due to the fact that Crash is a mute, and most of his humor comes from actions, while Cortex gets both to speak and act). The rest of Crash's enemies have gotten make overs, and for the most part, they look pretty good, even if some only get a few seconds of screen time.
Here's the thing, in this game you'll be playing as Crash, Cortex, Crash and Cortex and a rather short, but enjoyable, stage with Nina Cortex. Crash plays just like he did in previous games, without the bonus abilities he'd earn from bosses. Cortex trades Crash's spins for a gun, and loses the double jump. When Crash and Cortex team up, you play primarily as Crash, and can spin around Cortex or use him as a hammer, plus, throw him away to have him hit switches or attack faraway enemies. As for Nina, she doesn't have a double jump, but she can spin attack, and gets a hand that doubles as a grappling hook.
The game can be quite fun when it's not frustrating. The very last stage features a ton of very tight platforming sections(Over platforms on which Crash does project his shadow!), these are the most challenging sections of the game(which isn't saying much), but they were very well designed and were fun to get through, if only the rest of the game was this fun. Oh, and after this fantastic section... you are greeted with a pushing puzzle which quickly reminds you of how bad the game can get. And that's another issue, when the game is at its finest, the first stages, Nina's stage and the last stage, it's really good, but when it's not, it's pretty dull and frustrating. The game offers plenty of interesting ideas, like when Cortex is running away from enemies and Crash must open up a path for him, or when they fight over a crystal and you must move them together as if they were a sphere, but the game conspires against itself. Another issue is that you can't skip most cut-scenes, if you die during a boss, you will have to watch the entire pre-battle cutscene again.
Crash Twinsanity makes me kinda sad. There's so much untapped potential, so many good ideas, which I admit felt were gimmicky when I read about them, but after playing with them in the context of the game, they are fairly decent, but for every good thing the game does, it has a couple of catastrophic flaws that make it needlessly frustrating. It also started off so good, the first world is very entertaining, but as it goes along, it gets worse and worse...
