I think this sounds like it would fit well for a flash game in a scene inside a robot store. It has a very innocent quality to it, a bit child-like in a way.
I think the section from 1:21 to 1:52 could use a little more variation because it seems a bit repetitive at that part to me.
My favorite part is when the melody does the short little 2-second arpeggio thing at 1:19 to 1:21 and again at 2:15 to 2:17. If you can figure a way to expand on that short little bit and work it into other parts of the song, I think it would be good. But I'm no expert. Just my thought :D
