hi so i have version 7.1 of this game downloaded. i've only ever purchased one bundle from itch.io, and this game doesn't appear to be included. i was wondering whether this game was at some point free and that's how i have a copy, or whether i paid for the game and itch.io is suggesting i haven't. i'm just a little bewildered. i apparently played this game in september 2023; was the game free then?
