Flappy bird but instead Feces, perhaps if you improve it more you rename it Flappy Feces/ Flappy Fecal. Maybe add some animated wings to him or make him rotate a bit when jumping. I think it would also be funny to add him dropping some mini poops every couple of jumps. It could add a little more motion and visual fun. Furthermore matching the scale of background pixels to the foreground character. It looks awkward with a highly detailed character and then a 3 pixel pipe/ plunger.
