Rock Paper Shotgun recently mentioned (in their DevLog Watch, which bizarrely has so far failed most utterly to mention Limit Theory) a game in development called Prophour23.
In this game, each of which will last up to around 15 minutes, you construct an organism which must defend itself from insects. There is (unsurprisingly) a [url=http://forums.tigsource.com/index.php?topic=40628.0]devlog for it, as well as a browser-based demo that doesn't work in Internet Explorer.[/url] It's... different.
I scored 311 in my very first full game and have no idea how that happened.
