Summatorium

Summatorium is a math game where you will get an objective number to reach
and a bunch of numbers and signs that you must correctly use in order to
make a sume that gives the needed objective number as result.

GAME MODES:
There are three main game modes:
-Playtime Mode: excellent for just casual playing and keeping that brain mathy.
-Classic Mode: you have to face a countdown that will fall every time you fail to make the sume and will rise every time you get the sume right.
-Summatorium Mode: the same as classic mode but failing will make you lose.

HIGHSCORES:
Data is saved separately in each mode so you can compete with your friends to see who can reach the furthest.
