Yes, i did what i sweared not to: i reused the books code to publish (nearly) a Snake game! Which iteration is this: the 10th? Anyway, ours is best!
And partly, a post on this forum was 'responsible', where http://www.kongregate.com/games/netgrind/snakes-on-a-cartesian-plane was mentioned, and the lack of some of its variants for Android.
Well, it turned to something else, but we got heavily inspired. It's a hommage to LCD-handhelds in style, and citates some gfx from retro games.
It has 16 levels and a 2 player mode, there is pooping snake, portals and water etc.
If you want to know about an implemented feature, just ask!
