Please make this come out soon! Looks right up my alley!
It should be available soon. It actually went into Review yesterday, which means it would have been released yesterday (generally), but Apple disagreed with the violence classification I'd put on it and I had to make an adjustment. I'm hoping that it resumes review shortly and pushes through.
Good news... Requiem Z has just been approved by Apple and is headed to the App Store! You should be able to find it with a search now or fairly soon after now (with either "Requiem Z" or "Steve Jarman" - or possibly this link).
Be sure to let me know your feedback; things you love, things you don't love.
I already have some interesting plans for v1.1......
I'm looking forward to trying to beat your highscores
