There are 4 sets of levels:
- Grey levels (5) - for trainig - very usefull for novice;
- blue (30) - logical levels;
- puplre (10) - action levels with unlimited cloning;
- brown (27) - logical levels.
Note: in purple levels you can clone infinitely, use it - often just large amount of clones can help you, so you have to multiply them continuously.
Have a good time!
