Well, probably 8 years passed and i finally do it.
Also difficulty curve is awful... 27, 23 and 16 must be the last levels.
Also 2: achievement is missing.
This is a demonstration of the concept of the game, it is not an game and pretty lazy concept. The creator of the game can only be praised for the twelfth level, the rest is ridiculous. 1 point out of 20.
The twelfth level is the first level where you need to use logic, also (this is NOT a clue) you should know from one of the earlier levels that very large blocks can deactivate the springs. If you dont know this rule the solution may be very unobvious.
