That final thing with the Nickies really is the minigame from hell...
But the game as a whole is pretty good! Even if it's buggy and inefficient. And Little herself is just too cute.
Most of the animal intrusions are kinda far-fetched though. A large spider or a mouse, that's plausible enough. But you don't get frogs or snakes poking around in your living room unless you're living out there in the wilderness. And that octopus was really stretching things.
And why would the faceless protagonist dude use balls or pellet guns to save Little? He can just grab her and swat those animals off the table. The same thing applies with the Nickies; just grab Little, keep her out of their reach, and kick the little shits away.
