Here is the first screen shot of the game.
i've managed to finish the powerup implementation (all three of them).
Now i have to get to the Inventory and the main screen so i can call it done :)
its' a fairly simple game, requires that you understand the binary representation of numbers.
You can check out the code @ https://github.com/vkbsb/bitris or just download the zip and try it out. Has a results screen so you should be able to understand the score. :D
