Very difficult, but gets easier the more I try. As mentioned by others, the apples are very difficult to identify when they are small and that led to some frustration on my end when the time ran out. Speaking of time, it is difficult to notice and the correlation between the apples blinking and the time being low took me a while to figure out which led to some confusion. I'd suggest putting the timer closer to the center and have it blink with the apples. Overall, you have a some good ideas and obvious forethought (with the blinking apples); however, polish and other user experience factors make it more difficult to fully enjoy. Good luck with your future endeavors and with whatever you decide to do with this game!
