Perfect but,u need to use ★ to play and find clues in lab,if u don't have ★ u need to play puzzle or find things in the crime scenes,playing puzzle wastes more energy of my game character,and it's so slow to recover more energy,Im still on level 2 and I can't escape chapter 1 of this level because I need stars and my energy is 0 so I can't play puzzles,because of this iuninstall this app😢😕😑😞😞😞!!
