Yeah, I really enjoyed playing through it. Defiantly try the demo it's about 20% of the game, and it far enough that it sucks you in or not. Also you can use your save from the demo in the full game. If you're wondering according to steam I've played it and the demo for a total of 5.2 hours. And that's 100%ing the game, you could probably take longer but I kind of skipped a lot of stuff on my post first playthrough. It's really good. I also recommend looking into Digital: A Love Story which is kind of different, but still pretty good(and free).
EDIT: Oh, yeah it's more of a mature story and that, just wanting to point that out, and even with the cutesy cheerful look most of the game really isn't.
