Shouting into the microphone is fun and creative. I wonder how many people around you were scared while you were testing this? = D
The game is funny. Keeping your energy in balance knocks down the fun a little, but it creates its own complexity.
The game gave an error once (I can't describe exactly what was happening, but it was at the very first level):
ERROR in
action number 1
of Step Event0
for object oHitbox:
Unable to find any instance for object index '4' name 'oPlayer'
at gml_Object_oHitbox_Step_0

Good luck in development =)
