I thought alarm head & the player were 'joining' in that ending.
Also, if you wanted to say that without talking about themes, you're joining alarm head with cars. I reckon that's less of a stretch.

Thanks for playing! "Alarmhead" is a game that I've developed a few months ago, and recently I'm scheduling to start developing the sequel "Alarmhead 2". This kart game was kinda of a test project that I had a chance to make, thanks to GMTK Jam, and I've used a few models that may be present on the sequel for the main series. And about the ending, I've never thought about the fact that they're kinda ''joining'' at it, which proves that this game can have many interpretations.
