Hidden Dimension

This dimension is hidden from your observation channel.

How this works

You are a 1D controller — you see only Wealth (W). Your job is to maximise it by adjusting investment.

Environmental Integrity (E) is hidden. It provides the productivity that makes your investments work. As E degrades, investment becomes less effective. But you can't see E — only the dashboard.

When you hit the Reveal Hidden Dimensions button (or when collapse forces it), you'll see what your dashboard was missing.
