I am like the complete opposite of you, Kiruria. I can solve the puzzles really easily. My fastest time is 20 seconds for a hard one, and I have gotten to 30 puzzles on unlimites. I find the medium sized puzzles to be the hardest, because their frames aren't very distinctive. I am decent at berry picker, with my highest score being 139. I cannot, no matter what I do, get above 140. Head-it is kinda boring in my opinion. Also, when I play with a pokemon that moves a lot and it gets to a multiple of ten, it throws me off because it moves but the spot it hits from doesn't.
I have reached 5 stars in every level of all the games though.
I adore this feature and I hope it is always around in the games!!!
