Any suggestions for games where a run can be completed in 2-3 minutes? Or even less?

Mini Bowl is a Webgame that a good time is under 3 minutes, has an In Game Timer, and a very fast paced run where its just level after level. Definitely one of my fave games to run so Id always suggest it

where is 2012? on flash is pretty fun to run

Plants vs. Zombies has some fun minigames that can be speedrun in just a couple minutes.

Jumpnull it's a game where you cannot jump and most of the good times go under 4 minutes and it's not hard to get time under 4 minutes it's hard to get time below 3:40

2 games on my mind: Deepest Sword and Karlson. Deepest Sword can take 3-4 minutes while Karlson is about 1-4 (depending on how good you are).

Rodha’s 1-5 category is pretty short.

2d puzzle platformer. the first world takes 5 minutes

Citroen C4 Robot - a quirky little solo racing game. You have the ability to transform to and from a robot (the game was based a series of Citroen adverts). Car and Robot each have advantages and disadvantages for different parts of the course. The game can be completed in 3-4 minutes but has a high skill ceiling that hasn't been reached yet.

Try this one: Acts of Blood. Still a demo though.

Daytona USA and Sega Rally 1995 both are very short runs.
