The objective is to vertically stack up at least 3 blocks of similar color. These then will disappear and also activate any blocks of the same color near them. Any amount of blocks of the same color can be picked up at the same time. If you manage to destroy several blocks in a short time, you will get a combo bonus.

Special blocks
Currently there are two types of special blocks:

Grey blocks can not be picked up. They will change their color if other blocks are destroyed near them. Stars appear randomly scattered and are "catalysts". They can react with any color. Game Modes
There currently are 3 different game modes implemented:

Survival Mode - Stay alive as long as possible. Each second passed will get you additional points.
Time Attack - Get as many points as possible within a short time period.
Puzzle Mode - Try to solve the level destroying as many blocks as possible
Controls
Use the control stick or the keypad. Press left/right to move, down/up to pick up or put down blocks.
