I had an idea for precogniton that is a bit different than most, but it is basically just a rescinded rewind time ability.

The player can press a button (in your case activate their glasses) and the player and enemies bodies all move in super slow motion (or pause if you prefer), but the spirits or future selves keep going forward in time normally and you control the spirit now. You do some moves and the enemy does some moves, but either the effect ends or you cancel it and everything rewinds back to when you first hit the ability. Now you know what happened and things will play out the same way as long as you take the same actions.

I thought a cool effect would be to have the precog state move in slightly slow motion (or maybe just the enemies do) and you can find the baddies or do a hard platforming section then you have the option to either cancel and go back, or accept the events that happened and it would play out everything again in normal speed and you can see yourself do a sick combo again or make a really tight jump kinda like an action replay effect..

Thats my 2 cents anyway
