Octodad is a wonderful experience in so many ways, but most notably, it perfectly conveys a message of somebody so out of place desperately trying to fit in with the world, and how while it is a struggle, that somebody is accepted for who they are.
It's incredibly heartwarming in it's presentation, and in my opinion is the perfect length as well. At no point was I bored or disinterested in what was happening, and that's saying something for somebody like me. Sure, the controls are janky, but (quite obviously) that's the point! That just further heightens the message Octodad tries to convey, and honestly, if you find the controls to be a negative of this game, then you really have to re-evaluate how Octodad would be nearly as enjoyable with normal walking controls.
In my opinion, I never found anything to be too difficult considering the tone of the game, while at the same time having every objective still feel rewarding to complete. In a game like this, you walk a fine line between frustration and that rewarding feeling, and Octodad perfectly walks that line.
Above all though, Octodad incredibly unique, to where I can't think of another game that's similar and also anywhere near the same quality. I love it, and I recommend it to pretty much anyone looking for a good casual game to go through.
