Thank you for the kind words!
On the innovation angle. Take a look at the demo video. We added the ability to use a mobile device as a controller :-)
As for design. We used only two assets from a freely distributed art pack. The rest of the images, stages and characters were hand drawn by Eric. I did the voiceovers using Audacity's pitch and reverb effects.
Ah, I see you tried the phone. Cool :-)
