Squares Only: Lumines Quest

The core objective of the games is to survive by rotating and aligning 2×2 blocks varying between two colors to form 2×2 squares of a single color which will be erased when the Time Line passes over them. The game is lost when the blocks reach the top of the playing field.
A sequence of 2×2 blocks varying between two colors fall from the top of the playing field. When part of a falling block hits an obstruction, the remaining portion will split off and continue to fall. A vertical "Time Line" sweeps through the playing field from left to right. When a group of 2×2 blocks of the same color is created on the playing field, it creates a "colored square". When the Time Line passes through it, the colored square will disappear and points are added to the player's overall score. If the colored square is created in the middle of the Time Line, the Time Line will only take half of the colored square and no points will be awarded. Certain blocks with gems are known as "special blocks" and if are used to create colored squares, they will allow all individual adjacent blocks of the same color to be eliminate by the Time Line.
