Blosics (2009)

Blosics is a Flash-based puzzle-physics game where the player must shoot balls at green blocks to knock them off the screen. Doing this will award points and the player must meet a certain point threshold to move onto the next level. It cost points to shoot a ball, and the larger the ball, the more points it'll use up. The player must also refrain from knocking red blocks off the screen, as they subtract points from the score.
