I think I kinda played this game wrong because I didn't know how SHARECART1000 worked until just a day ago. Thankfully, it still stands up well on its own. I've had a lot of fun exploring.
EDIT: I think I just got to the end (or an end, if there's more than one) and oh boy. Oh wow. Nothing could have possibly prepared my eyes and ears for that. Thank you so much... this game was a journey and I was very glad to be on it.
