This is quite an intriguing find!
I had initially assumed that Thermohaline Nostalgia Studios had deliberately vanished and/or tried to remove all traces of their work from the internet, but if there’s an advertisement for CheeseSporker in another company’s work, then that could indicate some degree of communication, or even collaboration, between the two studios.
I wonder if Running Refrigerator Studios has any email archives or correspondence with Thermohaline Nostalgia Studios. This could potentially be an interesting lead.
