I have played it. It's very much a survival colony builder with a quirky and somewhat irreverent sense of humour.
Having also played KSP, I can tell you that aside from the genre there's a few definite and substantial differences between these games.
For one, unless you save extensively ONI is much less tolerant of errors of judgement and planning than KSP is, and slower to recover.
But if you like a decently complex colony builder that requires some definite planning and foresight to get things going well... it's a good game. And its sense of humour, while not the same as KSP, is of a similar vein.
