Level 22 IS the last level. No any further levels!
About the coins, here's their locations:
1. On lvl 0.
2. On lvl 3.
3. On lvl 4.
4. On lvl 5.
If u found the rest, I'll tell u only how to get the one on lvl 0:
bomb-jump to the left 1x1 square, then jump to the other 1x1 suare above u, again jump into that place in the top of the level and go to the very right, the coin will appear, and u can get outta there by putting a bomb where the white arrow will be...
I hope u got this...
