Gunpowder Universal $4.99 - $1.99
They just released this western puzzle game with the universal version, formally just on iPad, and now it is 60% off. People, and the developer, have been talking about it positively a bunch over on the main TouchArcade forums for Gunpowder. Probably worth checking it. I played the Steam (PC) version quite a bit and really enjoyed it despite not normally being into puzzle games at all.
