Tile Slider is nearly ready to go, I hope to have it released by the beginning of next week. I have several people testing it and should get feedback over the weekend. If all goes well I'll get it published by Monday.
I'm very happy with the way it came out, movement and gameplay is pretty smooth, high score tracking works well, all the things you'd expect out of an Android app seem to be working well. For my first Android project it came out well. I'm already writing up design documents for my next project, hopefully it comes out as well as this one.
