Hey! Dark here. You might want not to look into the images folder: that's where all the drawings are. 
I've made them hidden by default on Windows just in case you accidentally open the folder, but obviously I can't do the same for Linux or Mac. 
Sorry about that! You'll need to be extra careful on those platforms if you don't want spoilers.

I've made them accessible so you don't necessarily have to struggle through the game to see them, though it is a lot more fun to do so.

But you do you! Eitherway, thank you for having donated, it does mean a lot :)
