Revisit

Something I realized in hindsight with BerryBots is that a simpler API doesn't necessarily mean that it's simpler for the client of the API. In many cases, even the opposite. Consider that the "API" (instruction set) of a CPU is a hell of a lot simpler than the Java API, but for any real application I'd much rather be working with the latter. I kept the movement API in BerryBots to a single method to fire a thruster that alters your trajectory, but as a consequence you have to kind of understand vectors to make full use of it.

I'm not saying that you should make a user deal with complex 3-D physics or anything, just that there's a sweet spot.
