Level and experience points (XP)
In EXR, levels indicate your progress. You start with level 1. To level up, you need to accumulate experience points (XP). XP are earned with every meter you cover by rowing and by unlocking achievements.
With every level, the number of XP needed to proceed to the next one increases exponentially. This means that the higher your level, the longer it'll take to reach a new one.
When reaching different levels, you unlock new items for your avatar.
