I bought the game, tried to run, it doesn't start. It just gives me steam's "launching Sudokuball Detective..." pop-up again and again, till I close it before it disappears(and another one appears). Here's the log found on the game file. hope it helps. https://dl.dropboxusercontent.com/u/39289716/sudokuball_console.log...

Is this made by Unity? or other?

Is there a way to 'pencil' in temporary numbers? The option would be a great help in solving the later puzzles.
