As someone who watches and reads a lot of leftist theory this game has a ton of subtle messaging about anarcho-communism and might actually be one of the most progressive games I've ever played. All while being fun whimsical and a blast to jump through.

From the ghost at the start reminding you that dead people (ie. Dead old philosophers the left obsesses over) "don't have much to offer" to the ending where Mr. Sunshine is defeated largely by a worker strike caused by treating his robots unfairly this game nails it. Heck, it even manages to promote public transit! All while remaining captivating as hell while still looking like microsoft paint meets the muppets.
