Pretty well made short game, even if a little rough around the edges as the description already says. Nevertheless, here's some feedback for each area:
Gameplay: Most importantly the controls work well. Moving, jumping or shooting feel like they should and haven't failed me once.
As for the actual challenge, I actually picked up on the theme very fast on my first playthrough I took the challenges as a test and didn't defeat any enemies, stopped using my ground pound after I got told not to use it and so on, thinking that would lead to some sort of "good" ending. On my second run I experimented a bit more and noticed that I actually couldn't use the abilities any more.
Graphics: As described, rough around the edges. But still, the main character art looks nice and a lot of effort went into making the parallax background which really helps making the otherwise simple level design look good.
Sound: The music itself is really good, which makes it a shame that the audio quality in the third part seems subpar. I'm no audio professional, so I don't know exactly what went wrong, but maybe the output volume is simply to loud, crushing the audio?
