Hey there !
Glad that you enjoyed the update !
So, the main reason those blackscreen happen is because back when I was a beginner at Python I used "Fade" the thing is it's way too long, I never noticed it b ecause I clicked really fast since it's my game and I know every bit but it's a beginner's mistake, don't worry I'll do my best to fix it for 0.6, and I'll make sure to not repeat thatt mistake for future updates.
When it comes to grammatical errors well, I'm native french, so I sometime struggle with english, although I found great people helping me proofread the script, so with time, those errors are bound to disappear!
As for an option to hide the dialogue box, I'll see if I can do that for Android!
Thanks for the feedback !
