So, I got that flickering issue you mentioned, which I actually thought was intentional initially, as it was happening sort of in time with the music, but then it went a bit nuts and now I get what you mean.
Other than that, I absolutely love this game, and it's really impressive that you've done all this in just two days. ^^ Needs more plays!
(Also, the little nommy dude on the right arm is <3)
