It really reminds me of Invisible inc. Considering Klei have no desire to make Invisible inc into a series, this is a pretty excellent little spiritual successor. That being said, it comes with enough of its own ideas to be unique and an experience, that stands on its own merits. I'm having a blast with it and I hope the devs work on a sequel / DLC. It's got a lot of potential and is definitely worth playing. I haven't completed it, so I can't quite tell you how long it is.
