FlowEST

As the screen moves slowly from right to left, you just have to go with the flowEST. Click a creature to become them and then draw them a route to follow. You can alter their route by clicking into it.

You have to gather the red circles and can connect friends together. The yellow circles cause havoc, and if you go off the screen then just grab a new friend to get going again.

Just the mouse for all your actions.

Doubling up is fun but it will slow you down.
