As someone that hasn't even seen the first full season of Stranger Things, much less anything after...
The game has grown on me. If I have one complaint, the center toy shot is too damn hard to hit. It's wildly inconsistent on location, and out of probably well over 400 shots I've made to the thing, I've hit it exactly *twice*. It's a bad design. The rest of the game? Perfectly good. Decent rules from what I can make out, the flow is excellent aside from Mystery being lit every three seconds and that stops the ball. Multiballs are fun and rewarding.
I was a D- on the theme, but I'm like an A- on the actual gameplay.
