Paradox Embrace is a puzzle platformer in which you travel between different times to complete puzzles. You character can flip between three eras, using portals that exist amongst the platforms.
To progress you’ll need to find keys and potions, which will only be accessible in particular eras. You may need to move from the future to the stone age to avoid a machine, for example. While it could be very confusing trying to essentially play three games at the same time, the creators have put in a great hint system that keeps you on target, without making things too easy.
You can play Paradox Embrace from your browser, and it requires Flash. It’s not a short game, and thankfully your progress is automatically saved, so as long as you don’t clear your browser history, you’ll be able to play through at your leisure.
