This game has kinda inspired me to try and make my own but then I realized I don't have a wrinkly brain. So for now all I can do is support big brains like Rahis and annoyingly pester them to make more games.
Your statement is false, in fact brains are wrinkled to allow them fit more surface area in small space like the skull. So a wrinkled brain is smarter than a smooth one.
Anyone is capable of making peak like this as long as you are willing to spend the time and effort
