Vortex

How tornadoes pick things up and drop them inspired Vortex. The object is to succeed in trapping as many of the tornadoes as possible. Each tornado picks up and drops blocks at random. They can only carry one at a time but you can pick up three. The color density of the cursor will increase each time you pick up a block. If you have one or more blocks and are not moving you are safe. Otherwise, if a tornado catches you, it will pick YOU up and the game ends. It's not easy, the tornadoes you've captured may be set free by the other tornadoes.
