Please don't make a third one.
I find the music inappropriate and annoying and the game play boring because the figures are just not interesting to look at. I usually think spot-the-difference games are the easy way out, but I've played some that are beautiful and very well made. Not this one... you just made it more work by making everything excessively shiny and bouncy. Both of these attributes were simply annoying. The out-of-phase bouncing was unappealing to look at and confusing, because I couldn't figure out when and if it counted as a difference.
The "angel" tips are kind of cute and i like the title screen, but that's about it. Your skills would be much better used on a different project.
