I've decided to go with a price of $6.99; I think that the game's worth it, and I have a feeling that it'll go pretty well if it gets some honest reviews. If any reviewers don't already have the download details (for those of you who do, it's the same as the previous drafts) please contact me.
I've no idea how long it will be before it's available for download, hopefully no more than a couple of weeks. I'll post again once it's for sale, of course.
Many thanks to everyone who commented on my ramblings while I was putting it together - I hope that you'll think that the final results are worth it.
