Are you developing this game solo? If so amazing work so far. But I think this game has the potential to be one of the best games out on any Market/appstore. It's easy to use, has a social network feel, and fun to play. If you're solo you should look into working with others to further develop this game. I'd offer but I have no developing skills!
Hey, at the moment I am working solo yes, although I had a friend do the photoshop work for me. I have thought about getting some more people to help out, with an iPhone version and to spruce up the website with stats and leaderboards etc..
I will have a new version of the game up on the market soon, this weekend hopefully. After that I will be considering where I want to go from there, messaging is a big thing that people want so I want to add that in, and also there are some privacy concerns which I want to address(not showing exact location). I also have a background service in the works to notify you of nearby danger. Thanks again for your support!
*Also, if you like the game could you please rate/comment on the android market, getting quite a few one star reviews and comments like "Doesn't work, don't download", which is really frustrating because they generally don't leave enough details for me to fix/help, and it lowers the apps position in the market and can stop potential users from playing, and the game will be a lot more fun with lots of users. Also, the new version will sort out the force close issues people have been seeing, also some performance improvements in there, for those that didn't get it there is a pre-market build available here if you want a sneak peek. Thanks!
