Total numbers

The goal of the game is to ensure that all numbers in a row and column sum up to the total at the end of the rows and columns.

About the development

The game was made in zero hours. The clock starts ticking as soon as the time changes from daylight saving time back to normal. This happens once a year at three past midnight, the clock gets set to two hours past midnight and you have until the clock strikes three again to make your little game. With the emphasis in little, since you don't have a whole lot of time.

The inspiration game from magic squares and Nonograms, also called Hanjie and Picross. In a typical magic square all numbers when counted in each row and column count up to the same value. But I liked the idea to reverse engineer this. If given a set of row and column sums can you figure out what the value of the cells can be. Of course multiple solutions are possible for the same rows and column sums. If I had more time then I would have also included the diagonal for and added challenge.

I believe I managed to accomplish a lot, even able to spend some time on polish. For example if a row or column sum is correct the sum will become green instead of red, and you can use the arrow keys to navigate the grid. However I'm sure there are still plenty of bugs.
