I love Zachtronics' games, but they're kind of in the uncanny valley of gameplay for me. After a few hours, I start to wonder why I'm optimizing all these in-game circuits when I could be doing the same with my actual code! (On the other hand, they also make me realize how great Woz must have felt when he got Breakout down to just 44 chips.)<p>The performance comparisons to other players is a brilliant feature, though.
