Kinda wished it the gameplay was in a loop with different dialogue in each variation. After all, Char1 seems to be very knowledgeable of the game or at least has been making stuff up in order to set the lore of the world. That would have give some depth to the Ai in a sense that they know there's no end, but at least they would spend some more time with us. This would undergo the explanation of the creator and their idea of the intent the creator would unfold.
At some point when the Ai would have nothing to talk about, then they would offer a menu that allow the exit button in order to proceed with the difficult choice. After all, the game seem to be dialogue heavy. Like, you ought to spend some time with the Ai in order to really form a strong connection with it. The detail of them explaining on how they spending about a couple of years in active wouldn't necessarily hammer in the point. Then again, the character wouldn't be able to express themselves besides text.
I played the game four times to get a good idea. The game is well-made on the graphic aspect, nailing the atmosphere. The music happens to be enjoyable and would reinforce the atmosphere. Overall, I did enjoyed it.
