In 2017, a cartridge release was discussed for the game, but the response from Thorsten was that the game was so complex that it could take many years – the limitation was not RAM or CPU, but “Time”. He was very busy, managing a family with three small children, and so time to do the game was extremely limited. It seemed this would eventually contribute to the game being abandoned.

This sounds reasonable, the original game was the product of about 40 people working for about a year. Plus the four or five years some of those people previously spent on building their adventure game interpreter. Demaking a game takes less time than making one - you've got the whole game there already and you just have to figure out how to simplify it to fit into your target system - but it's still A Lot.
