Cylindix

A 2.5D falling blocks game where the blocks fall on a 3D-cylinder. The game is financed by advertising through AdMob, so it's also free. And it has app2sd support.

IMPORTANT: It's only for highend (and possibly good-performance midrange) android devices with VFPv3 floating point ARM CPU instruction set support (so ARMv7a/CortexA8 and better), and NOT for cheap lowend android devices!

It provides realtime synthesized chiptune music tracks and sound effects. It also uses OpenGL ES 2.0 with oldschool green screen framebuffer postprocessing pixelshader effects, so play it only on midrange and highend devices that support OpenGL ES 2.0.

The sound and music rendering engine is written entirely in Object Pascal and compiled with free pascal.

And it features also a global leaderboard through the Scoreloop social gaming platform.

The android permissions, which are requested by this game, are required by the AdMob SDK (INTERNET) and Scoreloop SDK (INTERNET/READ_PHONE_STATE).

You will see ads only in the game mode selection menu, on the game paused screen and on the gameover screen, and possibly a interstitial ad on the game-app-start. So otherwise except this, the game is so far ad-free.

So have fun with this first Android game from me.
