Quicksort (Yngwarr)

Did you ever wonder why your parcel takes so long to be delivered? Well, the delivery is a complex process, it requires many pieces of a system to work seamlessly and of course perfection can never be achieved, because of a disaster, or a blackout, or a system crash, or some self-important smartarse thinking they're so important and cannot be replaced... Which is pretty naive because they can. Even by robots.

You control a loader robot. The task is simple: they ask you for a specific crate, you take it to them. Every crate is labeled, so you shouldn't be confused, but keep in mind that color matters too. Robot controls are pretty sensitive, may require some time to get used to. Use arrows to move a robot and pick crates, Z then arrow to put a crate in a chosen direction. You can stack crates into towers of 3. Crates will come fast, so try not to get stuck under the "avalanche".
