Gunpowder is probably the "best" game we made at Rogue Rocket in terms of creativity and quality. We remain very proud of this game. It was originally a game concept we came up with and successfully signed with Microsoft as a publisher as an early launch window title for Windows 8 App Store. Unfortunately, the Windows App Store audience never really materialized into a healthy economy.
Fortunately, the team we worked with at Microsoft was very supportive and we were able to make a deal that allowd us to bring it independently to iOS, Amazon App Store, and Steam
We're very proud that it is nearly a 90% Metacritic scoring game (missing 1 qualified review), and 5 star user review average on iOS.
We also were selected as a July 2015 iOS Best New Games Featured in UK and Dutch App Stores, and most recently as one of the top family friendly games on the Mac App Store.
I wrote a blog article about how this game came to be on Gamasutra, which you can find here.
