suggestions
1: add 100 (transform number sprite into a font), you can now type numbers instead of click click click (largest number in "awesome calculator" is 99 so you do this to out-awesome the calculator)
2: add exponentiation, works like in "awesome calculator"

sprite concept
note: largest number would go from 100 to 1 trestrigintillion, or 100 googols (big number)
3: make so you can restart the game by pressing R (do this because it gets kinda annoying having to close and re-open the game every time you do 0÷0)
4: mac n linux supportuh 4 the people with no wind'ohs
