Fun and very intuitive. Played it twice and realized that the rules are revealed in the same order as their precedence (size>shade>shape). Also the sequence is never left to right, preventing me as a player from haphazardly solving it and moving on without having understood the rule.
Lessons explores the idea of teaching systems and tutorialisation in games.
What initially is a complex set of rules, systems and interactions is revealed to the player step by step.
There is no text guidance provided through play, each of the 20 levels provides further context for how everything works.
This is part of a series of games exploring communication between the game and the player. The other games in the series are:
