Unity was originally invented in Japan 1985 as “Chain Shot!” by Kuniaki Moribe. After that it has spread all over the world with names such as SameGame, TumeGame, KomeGame, MameGame, DebaGame, TileFall, Cabeem, MaciGame, GD-BMD etc.

The idea is to clear the whole playing area by removing tiles in groups. The more tiles you remove at the same time, the more points you get.

Changes:

* New keyboard shortcuts:
* 5 – New game
* * – Small board (star)
* 0 – Normal board (zero)
* # – Large board (hash)
* 7 – Take screenshot (was star previously)
* Settings: cursor wrap ON/OFF
* Cursor wraps around board edges
* Accelerator sensor support (Sensor API)
* Keyboard support to emulate Sensor API:
* 2 – Drop tiles upwards, shift columns right
* 4 – Drop tiles leftwards, shift columns up
* 6 – Drop tiles rightwards, shift columns down
* 8 – Drop tiles downwards, shift columns left
* Settings: down arrow ON/OFF
* Tested on: N77 (no sensors), N82 (sensors)
