yeap, i downloaded the free, and then the paid version, i liked it.
yes sprite sheets are the industry standards, but they have to be divisible by 16x16, 32x32, etc etc to be usable, when in the same sprite sheet you have different sizes, like the small and big haystack, or the carrots, where the carrot, the small and the big label are out of grid, then it makes it hard to be used :)
Nevertheless, a fine sprite pack.
I do recommend for others to buy.
