Orph

Orph is a dynamic puzzle game where you try to get a bunch of colored balls into the areas of their corresponding colors. The balls move nonstop according to the realistic physics of the game, so you'll have to move the walls to get the balls in the right place.

In every level you can move the walls, which usually have a small hole in them. The goal, of course, is to get the colored balls to the same-colored area while you keep the other balls from getting on the wrong side.

Some of the walls are stationary and have colors instead. If you touch one of these, the color will change. The rule is simple: a wall always lets balls of the same color pass through while repelling other colors.

Orph is a fun and original puzzle game with more than 50 levels. Its graphics are also very pretty, with a lovely minimalist style.
