From level 1 you can have light pieces (half weight)
From level 2 you can have heavy pieces (double weight)

At each level there is an additional set of pieces (more complicated at higher levels)
Chill mode: choose between 3 pieces and put them at your own pace.
Challenge mode: the pieces ascend in an elevator, so be careful not to delay too long: watch out for the upper limit. The speed increases with each level.
