Its an interesting concept, at first I didnt know mouse wheel was used for the movement of the numbers and the change in the pattern of course, but after i got the hang of this i managed to have fun with this, I like the minimalistic visuals and how it works, I would recomment make the lower area slightly bigger maybe, but its fine as is too, I rate graphics and fun on top but I like the overal everything, also, if you have time, please rate my game too, thanks!!!
