So, full screen isn't working, resolution settings aren't working, so these HD images are nowhere to be seen in the game. The game window seems to be less than 720 pixels high and maximizing the window just makes those pixels larger. What else isn't working?
Btw, I was never-ever-ever be able to play your TwinStar "game". It was always such a bugfest, absolutely nothing worked. I skipped months or maybe a year, a bunch of released versions, then tried again and it had even more bugs. So I classified you and your game as a totally hopeless case and ignored it since then.
So I'm not surprised at all seeing the same happening here.
Oh god...
And you're still trying to use (the same?) engine that you are unable to control or create a working game on it. A reasonable person would have switched to an engine that is easier to control a long time ago. Yes, Ren'Py can not export to html5, so what?! What's the point having that option when your game is hardly playable on the engine you're using? Which is more important?
So I'll skip half a year now again and then check back, have you been able to learn something by then or are you still just repeating the same pattern. Oh yes, and then I'll check your game again, is there something still working or has it just become a massive collection of unresolved bugs.
