I never got to finish the game myself because it kept lagging, not like "online ingame lag", but my browser acting up thanks to my dozens of tabs.
So I watched the youtube video instead.
The conversations were well thought out, with an actual "old player" that played with our main character during the game's life. There were a few others that are best left so that those who decide to read this before playing it don't get more information.
The other online player had a good personality given to it as well, giving a bit of context and some more stuff regarding the game.
The end was well done, and I can't say more.
If I were to rate it out of five, I'd say it is 4.7.
