Lol, nice bug. My specimen keeps dying without me doing anything. I gave him a book, he died. After that, the scientist keeps using things on him like stick or toy plane without my command and he keeps dying xDDD Well, kill 5 specimen achievement completed itself...
Implement what Darklord_x said, then I'd love to see badges here. Though the multiple choice is not the best to do for a picross. ;) Maybe you would do us a favor and correct that issue, too? I can't give a 5/5 for a game like that yet.
