The UI is hard to understand and read. The tools button doesn't work properly. The graph tab doesn't do anything at all.
One of my favorite math/puzzle games to date
This is a really amazing little math game. It's simple in premise, obvious in theory and difficult in practice. If you like math, and you like being stumped and you like the idea of a clever devilish calculator this game is well worth the small price tag.
A great game to get the mind going. Only complaint that i have is that the built-in regular calculator kinda sucks, I have to resort using a different calculator so that my answer from one equation can easily be used in the next equation.
A game about a haunted calculator asked me for a review. Who am I to refuse?
Really enjoyable
Funny math based puzzle game.
