While not the only amazing part of the game, without it the atmosphere and the emotions given by the game would be completely different, it's arguable whether it would be worse, but the game gains a lot from it and it's worth the money to listen in free time.

Gameplay is rather simple and that's a good thing; developers knew what they wanted to do and they did it well. The only bugs I've noticed was a few cases of dialogue not matching the voice over. The atmosphere from visuals, sound effects and music has really been making it easy for me to stay immersed and stop alt tabbing out the game most of the play, which I have a habit of doing on top of a bad attention span. The dialogue was humorous and thought provoking at times and I easily felt the relationship of the pair; it isn't just a pair of characters with some strengths pushed into it. Both have their traits and they shot it time and again that their relationship isn't based on attraction alone. And because I enjoyed the game so much, I have to be spoiler-free but specific about the few but big issues. The gameplay is relaxing and I could fly on Source for hours, but the ending just gave me an emotional pressure that I have to process first and while I can't complain that "it ended too soon" in case of P5R, this game took me under 19 hours with some AFK time and the ending came too soon and ended too soon, it felt like devs ran out of time and had to some cuts to fit a deadline. Each of the games from Mass Effect trillogy did a better job by putting some lighter, but still strong tension first, a little rest and then going full on. I understand that it was done to a degree, the problem is that the ending sequence was short and it began with the spike and the tension from before (free roaming bit) could've easily dispersed. If The Game Bakers read this by any chance, I hope you'll make at least one more game like this, because a sequel is going to be very hard with the endings given and a prequel is also unlikely. If that will happen, please make the game at least twenty hours before an average player is expected to reach the ending sequence, because the ending is the reason why I can't give full five stars and be fair about the rating.
