I'm O.K – A Murder Simulator is a 2006 freeware video game developed by Derek Yu, Chris Hanson, Philippe Jones, Alec Holowka and Christopher Howard Wolf.

[3] It was created as a satirical response[4] to a challenge by anti-video game-violence activist and disbarred attorney Jack Thompson.

[5] Thompson promised to contribute a $10,000 donation to the charity of choice of Paul Eibeler (then-chairman of Take-Two Interactive, one of the game companies most heavily criticized by Thompson) if such a game were released.

The makers of the gaming-related webcomic Penny Arcade have, however, made a $10,000 donation in Thompson's name to the Entertainment Software Association Foundation,[6][7] a philanthropic, grant-giving body run by the Entertainment Software Association.

[8] I'm O.K is a side-scrolling video game with 16-bit era low-resolution graphics that shares (to a degree) the basic gameplay (and somewhat lowbrow humor) of the Metal Slug series.
