Hahah lovely and with real kid actor?? It gives a nice touch too. I enjoyed it a lot, thanks and congratulations on the submission!!
If it helps, as a suggestion: music could have two states. One for exploring/walking, another one for "combat". Or maybe the same piece of music, with two different layers so the rhythm is continuous. Oh and maybe a third one when you run into the energy/courage items. Yeah, as audio person I look into those details :-P I hope it helps!
