Love the game, its  very challenging. The only thing is, is when you pass a level or 2 and can't 
pass that level, it takes you back a Kevel or 2.
Most games keep you at the level you passed to, even if you can't pass that level right away. Is
this normal for this game, or a bug that needs fixing? I'm a very loyal player, I made it to lv 40 and it took me back to lv. 38.
