Hey,

So the achievements on SweatShop are broken (as the game aswell), and the dev can't fix it so he did "enable" this bug/exploit/wtv you want to call it, that will give you ALL the achievements.

So what you need to do is, go in-game, and then follow this:

Press ESC - Space + G and you will unlock all the achievements.

I know some of you might be against this, but this was dev choice.

Cheers.
