That Extra Mode music was phenomenal (can't be properly described with just one word). I wish I could listen to it forever.
The only way I can describe the Extra Mode's music would be akin to finally reaching the True Final Boss, the absolute climax and finale, of a long and cherished game.
On a side note after figuring out what indicated which animals to abduct, I had a good time. The abduction sound complimented the music very well. The art and look helped out a lot too.
Too bad I can't get a seizure to experience all parts of your game.
