Life... and death.... something everyone experiences at least twice in their lifetime. Not everyone has the same amount of time in this world to make an impact like SwanBot did with Celestrium... He will be remembered for his great determination (albeit with many bugs and glitches) throughout his development process, recreating an original game that is not in the slightest like terrarium. And most of all, his f-fre... his friedship and his unique character will be remembered above all.
Oh but that has nothing to do with where he is now. I think he just got busy with real life things and couldn’t find time to work on SB programs.
