This game has its ups and downs. The upside being that the game runs 60fps, and the downside being the rest of the game. You have to go from room to room and read all the notes on the table (which is fine, of course there is nothing inherently wrong with that), but at the end of the game, you have these 2 characters explain everything. Do I think the game was worth playing? Yes. But I'm sorry, the pointless running around didn't need to happen.
But since this is your first complete game, and you're a single developer, I will say it is good. It honestly is really well made for your first game, but just try to make sure in the future (if you do put more notes on paper), that the entire game isn't explained at the end. I will give you a 10/10 for the storyline though, it was really unique! And the voice acting was also really well done, it honestly sounded more believable than 99% of the voice lines on this website. It actually sounded like you were going through this situation yourself, so well done!
