Pros:
- Makes you learn math-like problem solving
- You can exercise assembly language and have fun at the same time
Cons:
- Not too friendly for non-engineers
- Some levels are really hard

Overall, it's a game for a very specific audience. But if you are an engineer and love problem solving, you'll love it.

Performance:
Rushed out of the door.
When i first picked it up, it was laggy, unoptimized and ran at a low framerate.
Within the past year it's gotten a lot better, but it's still quite laggy.

Gameplay:
The gameplay felt quite novel at the time of release. But since then, plenty of other similar battle royale games came out, so the novelty value is somewhat diminished.

Anticheat (ATTENTION DEVELOPERS):
The only game i've played so far which permanently bans non-cheaters for running legitimate software (i'm guessing VMWare or AudioSwitch). If you're a developer who plays on his workstation, either avoid the game completely or make sure (check twice) there are no running VMWare processes in the background, or any other "Suspicious" processes. I cannot find a list of processes considered "Suspicious" by their anticheat - Battleye, so good luck.

Speaking of Battleye, it a virus-like anticheat system which sends data about all your running processes to a remote server for inspection. I understand having no cheaters in the game is important, but in my opinion that behaviour is overkill.

In case you do get banned, good luck -- PUBG support won't give you a specific reason for a ban, only quoting "Violation of the terms and services", and battleye doesn't seem to respond to appeal e-mails.

TL;DR:
Good concept, but laggy and not very optimized. False bans, overkill anticheat.
