Anyway the coins on lvl 3 and 4:
3: Where the right apple is in the beginning of the level, go there and jump, then as u get back down you'll automatically get the coin!
4: The empty level... jump from the right side to the left side (or from the left side to the center and back to left, which is pretty hard...
