Don’t.
What people here are saying: Don’t try to enter the dimension of suffering and pain.
What you are saying: OK. How can I enter the dimension of suffering and pain?
If you insist on entering the dimension of suffering and pain: Go a step further back and develop your game for DOS. Older Windows versions will just be able to run it out of the box, and everything else can run it via DOSBox.
I think you’re missing the compost part. Wood will break down in a compost, yet you can build houses from it. Indoor furniture made from wood will happily serve you for decades. Same with this biodegradable plastic: It’ll have a shelf life of decades or even centuries. When shredded and composted it will break down. This material is likely not a good candidate for the wheel housing on your car, but there’s no reason not to use it, for example, for a car’s interior.
