Wow that was a very out there concept, and that baby is too strong for this universe. Although I dunno, is the dad stronger? I mean he did chase after the baby and catch it on every single level, even through space. A bigger question though, how does the baby keep getting a mini gun, someone hide the miniguns!!!
Besides that though, there's some interesting ideas and a new little overall story throughout. The popups were great, the baby was dangerous and the environment was interesting in trying to survive the minigun going crazy.
That's bout it, a nice, kinda interesting mechanics wise game, with a kinda funny setting and overall pretty well executed. The only thing I'd really say is the audio repeated quite a lot, which with the baby sounds definitely got pretty annoying. Otherwise pretty awesome.
