Calcul8

Calcul8 is a quick fire math game. Remade from back when I did #90daydev.

AIM: to reach the number 0.

• Touch / Click buttons to subtract the number from your goal number till you hit 0.
• Press buttons again to undo.

TIP: the more buttons you use, the higher you'll score!

[UPDATE: there is now a refresh button in case you get stuck!]
