Let X,Y be two integers in [1,5] and [1,4] respectively.

To determine the score for each level, there are three intervening factors:

• The number of lives you had when you finished the X-Y level, named a.

• The remaining time at the moment when you finished the X-Y level, named b.

• The difficulty mode you chose.

Depending on your difficulty mode, different values will be assigned to the so-called "life multiplier" L and "time multiplier" T. The higher the difficulty, the higher the multipliers.

These are the explicit multipliers:

• Casual mode: L=2, T=10

• Easy mode: L=10, T=25

• Hard mode: L=20, T=50

• Arcade mode: L=50, T=75

Finally, there is a last multiplier, that depends on the objective difficulty of the X-Y level, that we could call D, as in Difficulty. D increases regularly, according to the following pattern:
D = X + (Y mod 2) * (Y/2)
The only exception to this rule is the last level, where D=10.

Finally, the level score S is obtained thanks to the following formula:

S = a * L * D + b * T
