Hello, thanks for your time playing my game.
The 3 coloured numbers under the life bar are statistics you gain from transmuting two or three items of same colour. Red affects your damage multiplier and slightly increases your health. Blue slightly increases your movement speed and damage multiplier. Green Significantly increases your health points. If you're curious about the exact numbers:
Health points increase by 20 for each Green point and by 10 for each Red point.
Movement speed increases by 20% for each Blue point.
Spell damage multiplier is: 2 extra damage points per Red point, plus 2 extra damage points per Blue point
I'll make sure to improve interface readability for my future projects, thanks for the feedback!
