Eh, everything is working fine, and I've been smoking for over 25 years, and the last time I had my lungs checked, the doc was amazed that my lungs were better then a 16 yr old non-smokers, that was 4 years ago, and I've cut back a lot since then (this translation non-withstanding), used to be a 20+ a day, now down to 3-5 a day normally, aiming to slowly drag that down over time.
as for my liver, I don't drink alcohol, just lots of tea, so should be okay.
anyway, as for the demo itself, I'm honestly leaning towards leaving things as-is until the full version comes out, as at this point its just minor things that I can sort when the full version drops. When the full version hits, I will be posting regular updates here like I did in the Monochrome thread so people know how things are going.
