In the end…
Well, just submitted my entry but not really too happy with it.
I think I fell into the trap of not having anything playable until very late on. I spent so long developing the gameplay mechanics (that is, trying to get them to *work*) that I didn’t really have time to make the most of the concept. What there is is the shell of an idea that was almost good.
Still, I think there’s plenty to expand on and improve on, and lots I could develop further if I want to. But I think I’ll have a day off from game development tomorrow!
The funny thing is, it didn’t seem like a complicated idea to start with. I had a pretty good idea of how I was going to implement everything, but actually sitting down and doing it became a real slog.
I’m disappointed, but then it wouldn’t be an exciting competition if you knew you would make a decent game every time. Experimenting and trying something new is all part of the fun, and you can’t experiment without the possibility of failing. So at the very least I can say I learned something, although I’m probably too tired to explain what it is!
I had a lovely time at CB2 Indies. Good luck to everyone else who was there, it was great meeting you all! I’ll be sure to return 
And good luck to everyone else who’s taken part!
