Collect all the colored balls in each level while avoiding traps, spikes, and other things as you build up momentum along the way. Reach the portal in one piece if you can.
You are given a task which must be completed using only two portals, align one portal in a position near your character, while using the other portal for teleportation. Constantly changing puzzles and obstacles are presented. Use momentum from jumps, ricochet techniques, items and other clever ways to get out of seemingly impossible situations.
