I like this game, I've completed it twice. It's ♥♥♥♥ing weird, which is what I have come to expect from Ice-Pick Lodge, and why they're probably my favourite developer. They never play it safe, and they're always trying something new.
Cargo is totally strange, set around a rather shakey premise (stopping the rotation of the planet would NOT "switch off" gravity... I'm just saying) involving harvesting Fun (the game's currency) from little naked dudes and conversing with these mechanical "gods" with grotesque circus masks...
The voice acting is dreadful (may just be a problem with the English version, the developers are based in Russia), the music is obnoxious and the controls at times can be frustrating. The story is convoluted and doesn't make a lot of sense, and the tasks the game has you carry out are nonsensical and vague. So why do I like it? I am not entirely sure, it just has a certain charm to it, it made me think about metaphysics I didn't expect it to and on occasion surprised me.
My recommendation is don't play this if you expect a polished or familiar experience, but if you want to play a game that is nothing like anything you've played before I can't think of many better candidates.
