Pratfall

Pratfall was a solo project made in Unity and published by armorgames.com in 2016 with over 100,000 plays.

You play as Elmer, searching through 3D perspective puzzles for the right place to take a leap of faith. In this dream world, one can walk up walls or step through portals to shift gravity. Reassemble your memories and wake from your coma. 

The portals in Pratfall were adapted from work done by Stanisław Adaszewski (https://adared.ch/) with three major modifications.  The first was adapting the portals from 1st-person perspective cameras to 3rd-person orthographic cameras. The second was transforming the cameras to project a true view of the portal exit for all relevant directions that portal may face (see the portal screenshots.) Finally, Adaszewski's work was expanded to support up to 4 simultaneous portal pairs.
