An eccentric, but not too bright scientist is stuck back in time after clumsily breaking his time machine. Now he must collaborate with his younger self and steal time machine parts from his far more succesful mentor. 

Paradox! is a single-screen 2D puzzle platformer that requires planning, logic thinking, and quick reflexes. 

Will the professor be able to go back to his time? Or will he create a paradox and suffer a horrible, horrible fate?


You play every level twice.
First, through the perspective of the young professor, you must collect all the chips scattered through the screen. You'll find deathly lasers and disappearing platforms. However, it seems like someone is giving you a hand, deactivating and activating the various objects... Avoid all the obstacles and reach the lift at the end before the timer runs out!

Then, play as the old professor. You'll see your young self completing the levels with your actions, but this time he needs a hand! Activate or deactivate lasers and platforms and make sure your young self gets to the end in one piece, lest creating a paradox. 

But be wary: if you slip up and touch your young self, this will also create a paradox, breaking the space-time continuum and causing time to reset! Thankfully you have a tricked-out cane stick and sick rollers to gain an edge.
