How to Play Tetraminoes and Round the Corners

The game uses octagonal slash faceted corners to make the bounces less chaotic. This turns out to be really important to know for later difficult levels. The physics would be slightly, slightly different for each ball because it's loading points and precision and stuff. I wonder how many people are aware of this consciously versus just sort of intuitive. And then Gabe Lane says he has been using hold downs corner bounces as an example of how to narrow down decisions in a physics game.
