Plane Crazy is a creative physics sandbox and that's exactly my problem with it as a runner. I tried treating build challenges like timed runs and the physics simply won't hand you the same result twice, the identical throttle input can send a build wobbling a different way every attempt. For a speedrun mindset that's a dealbreaker, consistency is the entire discipline and this engine is chaotic on purpose. It's genuinely impressive as a builder and flying a contraption you made yourself is a good time, but nothing here is optimizable in the run sense. Want to route and grind PBs? Not this. Want to mess with physics and build? Great. A middle 3 from the runner's chair.
