Avoid key pad style of number buttons

[GhostShadow0316]

1. Fir the 4×4 level, there's no need for number 5 and 6, theb why not remove them and make 1, 2, 3, 4 showed in a line?
   

2. please make the timer shows decimal, bc it sometimes makes some funny moment: Your best time is 17 second, and your current time is 17 second, you beat your record!

Thank you for reporting!

I fixed the second issue (regarding the best time) yesterday, this will go into the next release.

@GhostShadow0316 Regarding the first point: Do you mean that in e.g. 4x4 grids, the key pad buttons should be in a straight line? If I understand your intention correctly, the pencil marks in the grid should be in a straight line, too? Or did you mean something else?

after some thinking
you can make them something like

1 2
3 4

or

1 2 3
 4 5

for 5×5

just don't show the unused digit
