Creating a good game tutorial is essential to bringing people into a game but it is also one of the most difficult things to do. Making the tutorial for mushroom 11 was a challenging task. With its new mechanics and controls, the game had to teach players the basics, such as moving, shaping and splitting, before ramping the difficulty up. The developers chose to avoid text and hand-holding almost entirely, in favor of using puzzles to teach first time players. Julia will go over these puzzles, demonstrate their design and evolution, and discuss the lessons they learned (and relearned) as designers.
