Try Again

A physics platformer built to kill you, which is why it is called Try Again. You roll a ball toward a portal through seventy levels of floors that vanish, spikes that wait for the right moment, and rooms that behave differently on the second attempt than they did on the first. Nothing is unfair exactly, but almost nothing can be solved on sight: the first run through a level is reconnaissance and the second is the real one. A new zone and a boss arrive every ten levels.
