Calculational Integers

Calculational Integers is a 2-dimensional hand-drawn mathematical puzzle/shooter hybrid game where you learn basic mathematical concepts as in-game features. For example, the imaginary unit (i or sqrt of -1) is seen as a way of jumping and you can also wield a function gun and shoot enemies using it.

Face difficulties such as 0x, integrals, circles, thetas and more! Face the big boss, pi and survive or gain power-ups, meet the i c_dot and flip gravities! As long as you are never multiplied by 0, or reach the value of zero, you are completely fine!
