Nanaca Crash

NANACA†CRASH!! (sometimes affectionately referred to as "Zubaan") is a free online game based on the eroge CROSS†CHANNEL. It's about running into a boy (Taichi Kurosu) with a bicycle. The object of the game is to keep him flying in the air. If he stops, the game is over.

For some reason, it's extremely addictive.

Characters:
Kiri Sakura (blue) -- An easily upset girl who doesn't like Taichi. Boosts when hit. Her boost is a normal 45-degree impact. If Miki is the next person after her, her special is activated.

Miki Yamanobe (yellow) -- A good friend of Kiri. Boosts when hit. Hers is an upward punch. It's a little bit stronger than Kiri's. If Kiri is the next person after her, her special is activated.

Touko Kirihara (red, shown above) -- A girl descended from a samurai clan. Liked Taichi once, but not so anymore. Boosts when hit. Low altitude. A little bit stronger than Kiri's. If the last person you hit was her, her special is activated.

Misato Miyasumi (green) -- A girl with glasses. She can completely stop Taichi's movement, ending the game. However, if the last thing you hit was another girl (without bouncing) her SPECIAL activates, which includes using Kiri, Miki and Touko's boosts.

Hiroshi Sakuraba (brown) -- A friend of Taichi. Taichi bounces off him with an altered angle (up or down). He doesn't boost or slow down.

Tomoki Shima (light blue) -- A friend of Taichi. Slows Taichi down when hit.

Youko Hasekura (purple) -- A kunoichi. Does nothing when hit and disappears. If Taichi's next collision is with a female, she will intercept the hit, blocking it (unless one of Nanaka's SPECIALS appear - occurs when the second to last digit in the distance Taichi has traveled is 9). However, if Taichi hits a male, she will do nothing and let it happen.

Nanaka -- Hits Taichi with her bicycle at the beginning of the game. After Taichi hits Youko, Nanaka can teleport in when SPECIAL conditions are met, using one of her four special powers.

Taichi Kurosu -- The boy Nanaka hits with her bicycle. He flies.

Provides examples of:

 * Action Commands: Fulfilling certain conditions and landing on one of the girls gives you a limited window to getting an extra strong movement boost. Also doubles as a Limit Break.
 * Announcer Chatter: Who exactly is the guy talking during Touko's special attack?
 * Beauty Is Never Tarnished: Taichi seems pretty normal when he's stopped.
 * Bike Fu
 * Bishonen: Taichi, except after he's hit.
 * Bleached Underpants: The characters are borrowed from the PC H-Game CROSS†CHANNEL.
 * Butt Monkey: Again, Taichi.
 * Charged Attack:
 * Collision Damage: What the game is all about, actually.
 * Controllable Helplessness: Also what the game is all about!
 * Combination Attack: The specials for Kiri and Miki, as well as Misato.
 * Comedic Sociopathy: The entire premise-ramming a mentally unstable young man who happens to have sexual health issues and seeing how far your buddies can karate kick him-is rather sadistic. But damn funny.
 * Copy and Paste Environments: The background will repeat the same clouds and mountains over and over again.
 * Crash Into Hello: Nanaka crashing into Taichi with her bicycle at the beginning of the game.
 * Everything's Better with Spinning: Taichi spinning around while he's in the air.
 * Funbag Airbag: Quite literally happens if Misato stops Taichi.
 * In Name Only: Surprisingly averted. A lot of the characters' relationships with each other in CROSS†CHANNEL are pretty well summed up by how their specials are unlocked.
 * Lucky Charms Title
 * Panty Shot:
 * Kiri, every time she kicks Taichi.
 * Misato has one during her special, but you probably won't notice at first since Taichi's getting beaten up by the other girls at the same time.
 * Quad Damage:
 * Refuge in Audacity: In a world where a child in an auto accident is usually a scary or tragic thing, this game makes no apologies pummeling him as repeatedly and furiously as conceivably possible for comic effect.
 * Slapstick
 * You All Look Familiar: Aside from Taichi and Nanaka, there are 7 other characters in this game, and seeing as another character pops up on the screen every 10 meters, expect to see a lot of them.
 * You Fail Biology Forever: Taichi seems fine after getting run over, launced into the stratosphere, kicked, bouncing several times, and stopping dead when hitting a Meganekko, something that sould have reduced the both of them to greasy red smears.
 * You Fail Physics Forever: Some later versions have meters that give Taichi's velocity, either horizontally, vertically, or absolutely (with a little arrow to indicate direction and angle). Just calculating the forces involved will make the average physics student cringe in sympathy.
