Color Climb - Cascading tiles

A new twist on the "color flood" and "flood it" genres! Instead of trying to fill a board in as few moves as possible, test your quick wits by starting with a single colored tile and expand your control by copying the colors of the tiles around you as the tiles cascade down the screen! You've got to be quick because the tiles move faster and faster and the challenge gets harder and harder!

Instructions:
1. The game starts with a single selected tile in the bottom row.
2. Use the 5 buttons at the bottom of the screen to select a new color
3. The tiles adjacent to any selected tile will become selected if you match it's color
4. Use this to expand the number of tiles selected
5. The tiles will start to move down the screen once you have enough selected
6. The game ends when all the tiles you have selected move off the bottom of the screen

Note: Some tiles have power-ups on them which affect the speed of the game and help you survive longer and get a higher score!
