The developer's website (http://hcsoftware.sourceforge.net/jason-rohrer/
) lists his entire published portfolio. Critics of this game should try some of Jason Rohrer's freeware releases. What British mathematician John Conway did for games as procedural life generators, Jason Rohrer has been doing for games as statements about ethics and the limits of human consciousness. But while Conway's "Game of Life" is a wide-open laboratory, Jason Rohrer uses the medium of pseudorandomness to make syllogistic statements. For example, each step you take in "Passage" brings you a bit closer to the same conclusion: when facing a finite lifespan, the love you make is worth more than the treasure you take. Fairly straightforward conclusion, yet "Passage" is never hamfisted or forced - reasoned argument always trumps hand-waving assertion.
"Inside a Star-filled Sky" forgoes syllogistic logic in favor of inductive reasoning. As you traverse each level, you'll discover that you lack the attack power and/or movement speed to reach the exit. So, you must power up your creature and weaken your enemies. This means diving recursively into a powerup, an enemy, or even yourself. As these recursive levels stack up, you face the identical problem at each local scope: how to weaken the obstacles and strengthen yourself. All with an eye toward unwinding the stack and solving the original problem. And so the game politely asks the player to consider a simple proposition: observed causality in the universe is not a linear function of time but rather an ex post facto
selection of one set of points in a multi-dimensional space of possibilities, with each possibility perched on a stack of turtles all the way down. But the game actually makes this statement more elegantly than I ever could.
