Popix by Martin Magni is a game where you must destroy all pixels in a pixel art through having small balls collide with them. The game has 48 levels.

Gameplay

The game commences with a pixel art, and a series of small balls; mostly under the art, sometimes within. To shoot the ball, simply hold and then release. Theres a line to aim your ball while holding. The order what balls to shoot starts at topleft and ends in bottomright, and balls are shot in reading order.
Certain levels will also have barrier blocks (light gray) from which the balls can bounce. The game is successfully completed after clearing all of the pixel art blocks. Once shot, the balls will not respawn if it leaves, hence you have only limited amount of shots available from the balls present. You lose if you fail to break all of the blocks when all the balls leave. Some blocks move.

Trivia

There is actually an older version of Popix, with some notable changes:

1. BGs are differently colored instead of being just white.
2. You can control the power based on the length of the drag, and the aim is inversed.
3. Walls are stone blocks, and unbreakable blocks are considered unbreakable if the block is glued to another block
4. You can choose which ball to drag, and the balls are white and pixelated.
5. The blocks shatter instead of splatter.
6. The white outline doesn't exist.
7. The aim uses arrows instead of lines. It was replaced by a new theme in in Fancade 1.7.
