Wow, thanks for taking the time to give such detailed and helpful feedback! We did want to give some sort of indication when the birds went through the zoo gate (something flashing on the screen like "1 takahe saved!" or "2 ostriches saved!"), but we simply ran out of time. We're not sure what you mean about the muffled music in the beginning; we tested the sound on all our machines, and we didn't notice anything, but we'll keep looking into it. Anyway, thanks again, and we're really happy you had fun!
