In our second-longest ever, Mark explains the difference between an API and an SDK (and why it's important to know), Martha got her phone mugged and lost all her mobile game saves, and Stephen leads a discussion about designing for difficulty in your games (but mainly as an excuse to talk about fighting games again).

All this, plus your nice hosts celebrate 30 episodes, and Mark doesn't edit out something Martha asks him to, but only because Martha was the one who edited this episode.
