As a katamari tech demo, it's quaint and simple. While the graphics and colors do match the autumn vibe you are going for, I'm not sure about the music, which doesn't seem to specifically suit the autumn theme. In fact, it becomes quite jarring after several replays of the game. The controls are similar to katamari, what with twisting and turning, but the floatiness is bothersome. I also see that the controls use the space/enter key, but aside from using it for the start screen, I don't feel it affects gameplay at all.
