Zeroes is the mathematical puzzle game. You combine blocks on dots with numbers. Your goal is to combine blocks to calculate zero on each dot. There are five worlds in the game. Each world contains 20 levels with different blocks to use. There are blocks with add and subtract operations in the first world, multiplying and dividing in the second, diagonal blocks in the third, roots and squares in the fourth and the last world adds blocks with modulo operation into the mix.
The game has the funny mechanic of clicking on the different rectangle. Game shows how to play clearly too. These are the two things I liked the most.
I think that you could improve IU. There is no visual or audio feedback that you are touching the button for example. Game's font also looks a little bit too boring (I don't mean the logo, it looks well).
