If you've seen the meme, I think you'll understand the motivations behind my entry*:
"House Of Dangerous Kittens"
Basically you have to survive as long as possible against hordes of evil kittens. That's about as far as I got, but it makes for an okay demo.
I'm tempted to work on it further, it could be quite a fun game.
Technical things about H.O.D.K.:
- Written in C
- Uses SDL
- Compiles under windows and GNU/Linux
- Kittens eat you alive
* Actually I entered the 72 hour 'jam', rather than the 48 hour contest. It meant I could drink beer. Wayhey!
