Portal Proficiency, Level 15 $9050

Symmetric Freedom

Separating the wheat from the chaff, eh, BC Portal?

The cost of Symmetric Freedom is high thanks to the initial bridge. Without that complication it would be significantly easier to optimize for cost.

Extra challenge:

  • try to shave the cost – can you deliver a convoy for less than $10k?

Sample Solution:

After the bridge I opted to use a forward roll to trigger the upper right button, then convert a vertical level change into gap-jumping energy. After smashing the second button, forward momentum is regulated using a wall. Dropping down the accelerator shaft, a slow exit via the lower ramp completes the circuit.

The lower ramp may be obviated by clever use of the windshield rebound technique at the cost of 1 pair of portals. Can you find a way to make it work?
