The why:

To test the classes early on.

The how:

To level up to level 10, 10 xp is needed for the character(it will not be lvl 10 from the beginning of the game but after the first xp got
playing, around 10 min of gameplay you will be level 8).
The cap is set to 10 due to the game crashing after reaching 11.
