hey, thanks! i agree, the user interface for hearts solo leaves something to be desired. me and my friend steph spiffed it up a little for hearts net. i think she's going to do another new "theme" for hearts solo as well, so i can release a new version of that.<p>are you one of those people who likes to shoot the moon a lot? i tried to make the robots a lot more resistant to that this time around. the number one complaint i heard from my really good players was that it was too easy to shoot the moon.<p>i think my best marketing leverage at the moment is that hearts solo has been downloaded 30,000 times. about 5k of those were upgrades when i released version 1.1.0, so that's 25k unique users. when i release a new version, all 25k of them will get notified by the app store downloader. i'm going to try charging 99 cents, and see how many of them go for it.
