This was a really nice surprise and I think you did a great job as a very lo-fi title. The simulated IM brings a lot of nostalgia for me, and really captures that old Internet vibe. The idea of replaying and re-evaluating a dead game is something that I've really liked, and this reminds me of stuff like Agony of a Dying MMO and Pagan: Autogeny. Through the dialogue with Xander, you really convey the mix of fond memories and sadness of exploring an old game that people no longer play, and pepper the game with memories. The horror element is creepy and reminds me a bit of the 'game come alive' trope that you see in stuff like Worlds.com and creepypastas. I like the idea of a being hiding in the game, waiting to be let out. I think you could do a lot with that and take this game in a bunch of directions. Great work!
