Play a simulation game while learning grammar!
You will play as a fresh graduate of theoretical mathematics who put grammar in the fiftieth(ish) priority to learn (just after lighting a fire with teeth). Because of some mixed-up, now you are working as a grammar validator in the biggest grammar validation agency.
Use your grammar and management skills to work your way up from the “Junior Passable Intern” to “Editor Extraordinaire.” Upgrade your smelly apartment, adopt a pet, or ride a helicopter to the office. Everything is possible in Grammarian ltd.
