Well, I wasn't expecting that. I won't spoil it, but it goes in a somewhat predictable yet totally crazy direction.
I didn't really enjoy the gameplay, though. I had to get a calculator for some of the math problems, and when the genres did shift the gameplay was pretty barebones. I really love the concept, but the execution felt lacklustre.
I like the retro vibes, though I feel it's a bit halfhearted and the stock assets cheapen it a bit.
