Bah no sales yet today. This is unusal, but not a cause for panic (yet). Bandwidth has dropped back hugely, so I guess my earlier high sales were a direct result of high visitor numbers.
Im still fixing some bugs and improving stuff, but I won't get around to releasing a patch till saturday night at the earliest. Then it'll be time to assess whether to do any advertising for the game. Its hard to judge these things right without high enough numbers to use statistically, you need 10 or so sales a day I reckon to be able to judge if changes make a noticebale improvement, and I'm nowhere near that sadly ;(.
