Cool, thanks for the suggestions!
I've wrestled with the problem of how to teach the game a LOT. I've tried the voiced intro tutorial, a series of zachtronics-style levels, in-game contextual help menus, real-world manuals, and now the lego-style guides. Did you see those guides? They're very new, and I'd love to hear what does and doesn't work about them.
✔️ re: sensors that react to different objects. I also want to give people more control over tuning things like range and sensitivity.
You're the first to mention wanting to pivot pieces after placing them..... what do you think would be a good UI for that? People are already holding the mouse down when they're modifying a limb. Maybe if they drag an existing limb while holding down shift or something?
