- The FAQ describes editable invention-file sharing and silent video export, alongside 20 guided challenges.
Field notes
The described workflow ranges from goal-based challenges to an empty workbench, where players can assemble parts and test what happens. The FAQ says creations can leave the app as silent video clips or editable invention files for a friend to import on a compatible device; elsewhere, the page gives conflicting cues about whether the app has publicly launched.
