Doesn't quite reach the heights of Steins;Gate in my opinion and there are some questionable design decisions, both technical and story-wise. (no mouse support for the former, and for the latter, for some reason all of the endings are canon and are basically just chapters of the story that you can do in the wrong order? I recommend a guide to make sure you see stuff in the right order)
Regardless of these issues, it's still a fantastic story and I thoroughly enjoyed it. I was told I had to play Chaos;Head before this and it would probably be for the best if you did so, but I didn't really like Chaos;Head so I was worried I wouldn't like this. Fortunately, my fears were unfounded and this game does feel more akin to Steins;Gate than it does to C;H. (Although like I say, some things might not make sense if you haven't played C;H)
This has gotten more long-winded than I meant, but if you are a fan of visual novels and have played the first two Science Adventure games, then I highly recommend this. If you've just played Steins;Gate, I also recommend it. If you HAVEN'T played Steins;Gate then why are you not playing Steins;Gate?
