I've decided to quit my entry for LD52. It's not a problem with the theme or anything, I just don't feel like I would benefit from participating.

My first (and currently only) Ludum Dare was LD51. It was a chance to practice my game dev skills, test ideas, and get some feedback.

I don't feel like LD52 is having the same effect. Since last time, I've made a lot of progress on my main (commercial) game, and have a much clearer idea on what the finished product will look like. Therefore, I have no need to "experiment" or "practice" when I already have the necessary ideas and skills. Anything I create would just be an inferior version of part of my main game with the theme tacked on.

That's not to say I won't take part in more Ludum Dares in the future. There will be times when I need to try out ideas or get feedback. Now just isn't the time in my game's development cycle for it.
