the music when you're actually playing sounds suspiciously VERY similar to a song titled "olive rogue" from the webcomic homestuck. did you copy it, or just find it online and change the speed a bit?
within beginning the second level(it was labeled two...i think) i noticed enemies ive encountered so far do not visibly take damage. they die after a few hits, but it seems as if they dont,because the concept of enemies growing smaller/less bubbles was not taken from BT2 to BTA.
