QuadraPop

## Description

_QuadraPop_ is an action game similar to Tetris. Colored musical notes are
falling from above, in pairs. The player can rotate the falling pair of notes
and move it left and right until it lands. If at least four notes of the same
color are touching, they disappear and the player receives points. Sometimes,
a blocking note falls down; it can only be removed if a note next to it
disappears. The game level increases as the player receives score; on higher
levels, the notes fall down more quickly, but the player receives more points
for matching them up. It is possible to start from any level.
