The Experimental Gameplay Project

[TheJimTimMan]

Its alive once more! And they aren't waiting around, they've already got several new games up (this month's theme is "Unexperimental Shooter") plus archives of the games from earlier iterations on the site in case you find nostalgia is calling.
New horizons await: http://experimentalgameplay.com/

A few personal recommendations:

Attack of the Killer Swarm (EGP 1.0): Propel helpless civilians into the air as fast as you can in order to return them to Terra Firma in as earth-shakingly fast and splatiflying manner possible. I think my all-time best is around the mid-200's...

Frobot: I can't reliably describe this game myself, so I'll hand you over the site's description: Frobot by Kyle Gray. Play as Frobot, in this funk-themed arena shooter. Shoot business men to transform them into solid-gold dancers, and make yourself stronger. Based on the classic arcade game, Robotron – control Frobot using the keyboard and mouse.

Look around, and see if any of the games can steal a chunk of your spare time from under your nose
