Quoting from the event website:
Ludum Dare is a regular accelerated game development event. Participants develop games from scratch in a weekend, based on a theme suggested by community. After the competition ends, participants are given 3 weeks to play and rate games created by their peers.

It really is a great experience and we love to participate in this event whenever it takes place. We strongly encourage anyone who wants to/does make games to join the event!

Here are the games we made during the previous LDs:

E-VOLV (LD24 – Evolution)
by Valandre
An original take on the side-scroller/shoot-them-all genre where you grow your defenses by gathering pieces of your destroyed enemies…

Promoted! (LD24 – Evolution)
by 01101101, Carduus and Mathieu
Make your way to the top of the corporate world. Make coffee, be a good recruit, handle lazy employees, become a mercyless shark.

Exposed (LD23 – Tiny world)
by 01101101, Carduus and Mathieu
You destroyed one of your mad-scientist/uncle’s World Balls and the creatures on it… Now make up for it, take a new one, use whatever you see fit in the lab and show Evolution who’s the boss! ;)

Hamster Damn (LD23 – Tiny world)
by Valandre
Help Ally the Hamster to prevent the fall of the night! Collect sunbeams and bring them to the sun before it disappears…

The Traveler (LD23 – Tiny world)
by Thorvald
A puzzle-platformer set in a snow globe… Run, jump, and of course, shake!

/follow (LD22 – Alone)

You like your peace and quiet, but this daft bodyguard won’t leave you alone. Will you be able to outrun him?
