Totally understandable, because there's no real objective. :D
"Even if you don't complete your game as you intended it, it is still desirable to submit your unfinished game. The idea is to watch your progress, and give you something to compare your future work to, as well as give others encouragement or ideas for a game."
The vivid description of my game was there just to inspire me. Now that I think about it, I might be able to work at EA with my skill of over-promising and under-delivering. hehe
I used this more as a programing practice.
I think I've added the entirety of the game logic within 3 hours.
Actually I just wanted to make it anything but a still image. So that's what I ended up with.
P.S. If you want to see some really beautiful code, look at #'resolve-tile-sprite in tile.lisp.
