This game is incredible for the niche of people who love to program and problem solve for fun. Following the game's recommendations, it's hard to express how charming it is to print out the language spec, datasheets, etc and put it in a binder with section dividers. Very much worth the cost for the enhanced immersion and fun. And it's a convenient place to write down the tips and tricks you pick up as you learn. It's a challenging game, but very rewarding. The chatter between your coworkers is entertaining, and there's a bit of throughline to the events of the game. It's all very well done. I can't really recommend this game to anybody I know in real life, but it hits the spot for me.

Might need to watch a video first on the first 2 puzzles to get a idea of the game and how it works, then off to reading and fun you go!
