An abstract, experimental game about playing games.
I found a couple of bits kind of funny, but it felt like Unnamed really didn't go far enough to drive home the points it was trying to make. One could argue that the game's length accentuates part of what it was getting at, but it seemed more to me like the developer was either rushed for time or ran out of ideas.
While I agree that there are a lot of boring and unoriginal games out there, pointing it out in yet another boring, unoriginal game only makes the pile larger. Yes, this game is unoriginal - it's pretty much a knockoff of The Stanley Parable, only much shorter and not as well thought out. Perhaps it's intentionally mocking TSP, but that's probably giving Unnamed too much credit. It would've been better written if that were the case.
I guess the best thing I have to say about Unnamed is that it's short, which is at least preferable when it comes to enduring a disappointing experience.
