So does anyone know why 0.3.15 version crashes ? Like flat out on second screen after clicking on continue it freezes and crashes. I am running it in sandboxie as I dont trust pretty much anything is being uploaded here, so I am not gonna run it ouside of that - which might be the reason for it, but I never had issue with that outside of some corrupted files here and there.
Nothing against a pinch of suspicion/mistrust, when it comes to stuff from the internet.
Except for the Vikingfiles, which I don't know if they are Lyrical's or F95-staff/uploader links, the others are our own. Otherwise, to be sure you get the original files, you can find those links in our discord as well.
For the issue at hand: You mean the splashscreen, I presume? That's basically a Quit and a Return button as well as... the SnowBlossom Sprite class for a sort of particle effect.
As far as I know, Ren'Py has some issues in virtual machines, relying on the graphics hardware of the machine and that might cause the issue (as does the issue of Ren'Py not playing movies in VMs, apparently)
What you could try is changing the renderer. When you start the game by e.g. double clicking the .exe, immediately press and hold the [shift]. After some time, the game should open with a grey screen and some options.
In the top left, select ANGLE2.
ANGLE2 translates OpenGL/GLES to DirectX 9 and/or 11 (depending on what's present, I think) and is used if e.g. Windows has no or only limited GL support. That might be a solution to e.g. your gfx not being directly accessible in the virtual environment or only through translation layers like DirectX.
