It's been a while since this post has been up but I'm amazed and flattered by Lanwolf's dedication to finding all the lore drops. It's more enthusiasm than I ever expected anyone to put into a game I've made and it makes me super happy.
HOWEVER I think I've made this task a living hell for him by being a dumbass and not implementing any way to see all previously obtained loot drops and making him manually go through all his save files. So a quality of life improvement I'm adding to the eventual 0.4 build (we're working on it guys, patience) is the ability to see all the files obtained across all playthroughs (from now on) from the main menu.
Again, thank you Lanwolf for putting all the time into this, I hope we continue to deliver.
