If your family wasn't suspicious of your tentacles masked only by a suit before, they'll certainly be wary when they're flailing around like a wacky waving inflatable arm-flailing tube man.
Or when Octodad is freaking out like he's being overtaken by demonic possession. Half the time it looks like he's trying to walk through dimensions, stretching out and morphing into weird forms. The other half looks like he's having a weird trip out session, Xavier: Renegade Angel style.
Basically it's very weird and you should watch it. Before bed. With the lights off. You're welcome.
Oh, and in case you were wondering, these glitches have since been fixed. This was early development stage fun. You can see the official, non-glitchy but still weird trailer here.
