Well, this game was fairly poorly designed, but there was no way I could hate it. It was when of the simplest games I could play that had medals. Yes, that is shallow, but it's not terrible at least. I thought the music used was decent and I appreciated you wishing someone a happy birthday. Again, it could use a lot of work with the graphics. Of course, it probably wasn't meant to be anything that good.
You should make it so that your goals are not layed out so easily. You should have a bunch of harder stuff to do like fight enemies or something. The single blue block guy wasn't much of a colorful touch, either. At least this is a harmless game. Just try to work on more detail next time.
