To be fair, '0.548744' is a weird way to write '0.1'. I'm excited by the prospect of another QSP game, but with how this guy numbers his stuff I guess we have to wait to v9.3 for serious content? Will add to the watch list.
The framework is an exact dupe of SOB except for different icons, but the titlecard uses the same hollow blue letters for menu buttons. This makes me think it's either on purpose and the dev is trying to make the game look as much as SOB as possible OR they have the original PSD file which brings many more questions with it. Curious where it goes and I will reserve judgement but this looks fairly suspect.
Don't get me wrong, I've dabbled with maybe making my own QSP, and the framework of SOB is solid so certainly worth considering as a foundation, the CSS and Java files attached already make sure saves work, everything is colored and aligned correctly etc. So this might just be someone that's a fan of QSP and just hollowed out a .QSP and the Standalone_content folder and started putting their own stuff in. That's probably roughly how I'd do it, and then let the story and choices be what makes it a different experience from SOB.
