Aww, I love this game. While it's not that innovative, it works because it has freaking Derpy in it! I just love how sugary sweet everything in this game is! You get a wonderful sense of being in Ponyville. I believe these are all real still frames from the show. I think you added the muffins, though.
Funny, she only mentioned muffins once, but now has a weird obsession. I thought I had seen this before. It must have been the previous installments in the series. The music is great too. And hey, you did submit this on the day an episode premiered, specially the Breezies one.
