The Tiny World Inside Everything

Like Duolingo, but for The Tiny World Inside Everything. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

For the part of you with thirty open tabs that never became anything.

A short one: 26 levels across 3 sections, about 52 minutes end to end, roughly 10 days at five minutes a day. It moves through Building Your First Universe, Meet the Tiny Team Members, and The Energy Hidden Inside. It starts from scratch.
