Hence my confusion. I don't know how to find out more about what's going on but apparently zachtronics as a company is owned by 'Alliance Media Holdings,' and the DLC release coincides with the addition to the Nintendo store, so I'd guess we have the company that bought the IP hiring someone to port it to switch to get access to an untapped market segment and adding a few more levels via DLC to the PC version to kick up some buzz amongst the older players and help sales.
