1) Flying bots move super fast and the missiles almost instantly hits you. (I play on 120hz monitor, I wonder if that has anything to do with it).
2) I got 582-587 coins at the cemetery, because some of the flying bots just disappear after you hit them. Especially the one that is right after Dr. Phil and you punch it to the right. I tried it the second time as well and it did happen again.
3) Flying bots are waiting at the floor after you hit them when you go after them later.
So mostly bugs are about flying bots and nothing else.
Really runs great, awesome game so far. Can't wait to see the rest of the game after the cemetery when you get those "features" fixed :)
