This was an unexpectedly chaotic take on 'one button'. Like, I was kinda expecting the sort of games that get abstracted out to only use one button as the control, not this sort of 'the one button is all the controls at once'.
In other words, this game was pretty bad, bad enough to be great.
The utterly absurd humour in the rest of the game was just icing on the cake, and it was a perfect festive game to play in June.
