strange that the save didn't work for me... I had several hours in and had unlocked ghoul...all maxed on headless, and top bottom buttons on ghoul were maxed, though only about two thirds developed on the price one in the middle... not worried about you sending a file, I may try to play again and see how/where to save if you could share that with me.
I do think the players who think it is broke, do not realize you have to click and hold for the third step of creation. (I didn't the first time either, had to reload and mess around a bit before I noticed it... maybe not a bad idea to add that instruction so people won't automatically think the game is broken?)
Keep creating...
