You had the mechanics down, the art style is cute, the music fits well, but the level design needs some serious work. The bird is literally unavoidable in level 1, and the jump right after the bird is way too difficult for level one stuff. Also you can use the A and D keys to move left and right but only arrow key up jumps? That's an odd decision or bug. Still, it had promise, and if this is your first game, it's not a bad attempt. The art as I said is cute and fitting, and the music is pretty good!
