Love the music and models. The animations made it easy to understand when the attacks would come. I was able to run right by the surveillance cameras, I never had to stick my head in the ground (it was still a cute addition, though). I don't think it quite hits the theme, as all you're doing is collecting enough ostriches to get to the end.
It would be nice if maybe the ostriches could attack some of the things depending on how many you have with you. Like two ostriches together could take out the lasers, but three could take out the killer roombas, etc.
But overall, well done! Made me smile. :)
