Thanks! appreciate the comment!
You can be on the present or the past,, you switch between with -R-, you cannot touch the magic circle when they're big(the small one dont do anything to you) or you get back at the beggining, same with the falls, if you fall from to high, you restart( my bad there, I din't explain that on game)
For destroy the circles, you can go back in time, and interact with the orbs with -E- some circles can get destroyed like this, not all, and when you get back at the present they not longer there.
To avoid the falling damage you have to jump on the wall in front, and wallsliding, you can also walljump!
Hope you can beat it, if you need something else tell me!
Thanks for playing it! :)
