Thank you so much, CaCh, for making this update, and I'm back with another bug report and some suggestions. For the bug report, well, its kinda weird, whenever I use the nails from the hand tool, when I click them again to get rid of them, they do detach, but the nail is still displayed. This stays through resetting and going to the main menu then going back in again. The only way I found to fix it was to completely restart the game.
Now, the suggestions.
1. Maybe have the bleeding not stop so quickly. The human body has a LOT of blood, in fact, 1.2-1.5 gallons/4.5-5.5 liters of it. I would also like to see him slowly bleed to death, like he can only bleed but so much until he dies from blood loss. This would go good with bandages so that you could stop him from bleeding. Plus, every vein is directly or indirectly connected to every other vein, so all the blood in your body could drain out from a single wound, thus having the bleeding continue until your are completely out of blood.
2. Maybe something to revive him, like defribulators. They would revive him, and also bring back a little sliver of health. But, they would only work as long as his head is still attached/not damaged, and if his heart was still not damaged. Or, simply if he has lost too much blood, it also wouldn't work.
3. Maybe have him not just die instantly from a stab to the middle of his chest. People have been stabbed 10+ times in the chest, and did they die instantly? No. Just because your heart is damaged, doesn't mean you just instantly stop being alive.
