I'm OK

I'm O.K - A Murder Simulator is a freeware Beat'Em Up Platformer game created in 2005 by Derek Yu and others in response to Jack Thompson's "A Modest Video Game Proposal", a letter in which he asked the Entertainment Software Association to create a videogame involving the mass murder of videogame industry employees. Thompson claimed that he would donate $10,000 to a charity of Paul Eibeler's (former chairman of Take Two Interactive, a company heavily criticized by Thompson) choosing if such a game were made.

This game involves... well, rampant cartoonish over-the-top violence against video game industry customers, vendors, developers, and executives. In the course of several levels the main character, a distraught father named Osaki Kim (O.K. for short) whose son perished in a videogame-induced shooting, goes on an angry rampage to avenge his son's death.

(Thompson later reneged on this promise, saying that the game had to be commercially published and sold. He later even tried to sue Penny Arcade when it donated the $10K in Thompson's name to the Entertainment Software Association Foundation charity.)

Tropes used in I'm OK include:

Arms Dealer: Where you buy ammunition between levels. For fun, try poking him with your cursor.
Batter Up: from Thompson's letter, describing the weapons Mr. Kim should have access to: "even baseball bats. Especially baseball bats."
Berserker Tears: Osaki never stops crying.
Bland-Name Product: one of the bonus stages takes place in Beast Buy.
- Beast Buy, P.U. Games and Mal-Wart, to list them all.
Boring but Practical: Nothing clears a room faster than the submachine gun.
Classic Cheat Code: Entering the Konami code on the title screen shows an... interesting cutscene.
Collapsing Lair: The final obstacle, and no, there's no checkpoint in that level.
Dance Battler: Azn_Dragon and his Dance Dance Revolution arcade cabinet.
Demonic Spiders: Goddamn attorneys!
Giant Space Flea From Nowhere: The final boss WOULD have been the developers of the game, but they were stomped on by a giant Mario with a Tradesnark™ symbol above his head.
Hide Your Children: Completely averted. The first level has you exploding children's heads.
Incredibly Lame Pun: Too many to count.
Ludicrous Gibs: Every enemy type has an over-the-top death animation. The attorneys, for example, vomit fountains of blood.
Machete Mayhem: It's a throwing weapon, for whatever reason.
Murder Simulators: This game is one designed by the Trope Namer himself.
No Celebrities Were Harmed: Paula Eibel (for Paul Eibeler), obviously.
- Also, you know, Jack Offson.
Soundtrack Dissonance: The entire second stage is set to a 16-bit mix of "Lawyers In Love" (At Jack Thompson's specific request).
Take That: This is a videogame made entirely as an Insult Backfire, and it is actually fun to play.
- Made by Thompsonsoft. "We'll do anything for attention!"
Unexpected Gameplay Change: The bonus levels are gallery shooters. Ready your mouse.
Urine Trouble: Osaki Kim inherits the peeing button from Postal (again, at Jack Thompson's specific request). In addition to desecrating brains, the pee also functions as a fire extinguisher.
