Well, I started a thread in 2003 asking about Quest games entered in the IFComp. No one entered a game. I did the same in 2004. Still no one entered a game.

Here's 2005's thread: anyone planning to enter a game in this year's IFComp?

Nope

One game in development at the mo - if you can call it that. Should be a short-ish entry into there if I get around to making it for next year.

I entered the IFcomp 2005 with my game made for Quest

BUT

I hoped it could be finished sooner, and I hoped someone could help me with the english in it, for beta testing and correct some language mistakes, but I was busy finishing my inform game for the French mini competition (deadline at the end of september), so I prefer delaying the release of the Quest game for next year, I don't want it to finish the last in the comp.
I'm also not using windows any longer, it mean I have to use an emulator for testing / playing my game, which make it less attractive to finish.
