Inversion

Based on the mechanics in the movie TENET. The game works in phases.

Phase 1: You are experiencing the normal flow of time (Red). Your goal is to do what you need to do and then make it to the turnstile.

Phase 2: Once you go into the turnstile, you are now inverted and come out the other side (Blue). You will be able to see your past self (Red) and can take advantage of the effects of what Red has done to make it to the turnstile before time gets to zero.

Phase 3: Loop is closed, you can now view what it all looks like since it is all happening at the same time.  

Hint: You gotta stop thinking in linear terms - Don't try to understand it. Feel it.
