well hearing problems here also
I am not a english native but my english speaking and hearing is rather good if i might say so. Still it was very hard to understand what they are talking, most of it was like "word -sound-sounds-sounds-sounds-word" in terms of understanding. so like 50% if not more was just me guesing whats going on. Either you had your lips to close to the microphone or the volume was just to high, both ways - to much "bass". Aside from that i quite liked this animation. but really if you could record a better, more "clear" for ears audio version it would do wonders.
