Gain lives everytime you die? I haven't found that one. Do you have a clue how to reproduce it?
The one I have found after submitting the game is if you press home when you have exactly 1 life left you get endless lives. Yay! =D Game Over Screen launches only if player dies on a bomb / spike. And it only checks for 0 . Not -1,-2 etc. So if you feel sad for the poor Kitty loosing her lives, you can make her Immortal!
I'm not Even sure if I want to fix that bug. It would be fun to let players cheat death also. Like an easy mode or trainer. Like the old computer games had. Obviously the true ending could not be achieved by cheating 😉
