I am one of two developers of a new puzzle game for Android called 'Pipes 3D'. We have recently released it on Google Play Store and would like it very much if you guys tried it.
Description: it is a flow/numberlink type game in 3D, where you connect pipes on the surface of a cube to complete a level. As of now, there is 500 levels, with more coming in the future. There are 5 difficulty levels, ranging from very easy to very hard. The graphics are customizable, as a result, many devices can run the game in good framerate. We have also integrated Google Game Play services with achievements and leaderboards! All feedback and questions are very welcome! We hope you guys like it.
