I played this too. It's certainly a feat for a solo dev. It's very well made regardless. It's cute. It's mostly a breeze so I just kept playing last night to see what's next (up to boss 3). But it doesn't really grab me to go back either. Not like Poi or Skylar & Plux (my favorite indie 3D platformers so far, I think they're excellent and every fan of the genre should get them, Poi more Nintendo style S&P more PS2 style). Maybe it's a mood thing. I also just skipped all the post/pre-level cut scenes, they just seemed to be recaps of what I'd already seen in-engine. Jack did this, went on his way to that.
