This game is really addictive and fun but it can get frustrating at the same point.
Sometimes it turns out in the middle of a level that you have already spend to much moves so it is practical impossible to beat the current board. at this point all you can do is to make your remaining moves and then start over again - all over again. and that's frustrating. you should - if you would be encouraged enough to work on a two years old project - add at least some kind of extra lifes or something to eliminate this problem.
