I wrote a basic zachtronics style puzzler based around 0x10c, its one of my favourite concepts that's always stuck with me. I also strongly feel like it'd have a player base (at least initially, while everyone's coding) of maybe a few hundred people worldwide, which makes it a terrible decision financially

I feel like you're stuck between a rock and a hard place with that game. Do people really want to build their whole own OS just to interact with the hardware of their spaceship? Should it be a game where you have an ingame software market, for people to buy/sell software to use in your spaceship controls? Is a player REALLY going to build windows 3.1 for the DCPU for free?

I'd love to make it work, there was an open source game that was going for a while, but it went all the way down to the BIOS level which is just.. way too technical for most people. Who wants to get involved with an API/ABI for just making their spaceship move?
