Great game. I wanted more levels when I finished.
I think the jumping while bouncing movement could use a little enhancing. I ended up holding down the space bar while bouncing to get through all the ghosts. Not sure if that was intentional.
Another thing that could help is give a little more platform/spacing when re-appearing. There were a couple times where I just fell on spikes after dying because I was still holding forward.
I feel for this microphone(?) thing and hope they find what they are looking for.
