Well, day two and set two nearly finished. Only missing are level 2-6 and 2-9. But I will not despair and finish those remaining ones.
Your game deserves all the time spend on it. It is just as hard it as to be, so it is enjoyable... Even if some levels are harder to finish :)
Edit: As I unlocked set 3 by finishing 8 levels on set 2, I saw you made some levels which are really hard, especially with the bouncing tiles... What a neat idea :D
I fear what new trick you add to the last two sets of levels... I don't wanna know for now!
