Hey bro, a friendly advice. I opened your script file and saw that you're using "show" with every picture. That's a really bad thing
Because the engine basically keeps every "show" picture as a separate layer, and adds another above it if you don't use "hide" right after. So as the game becomes longer, it has to keep more and more images hidden behind each other. Big games written like this will slow down the PC eventually grinding them to a lagging mess. By the time players are at the end of 0.5, they probably have like a thousand pictures layered behind each other
You should change every "show" statement to "scene" statement, that way it automatically clears the previous picture and you don't have to "hide" them 1 by 1.
so the lines like
show day1_4
should all be written like this instead:
scene day1_4
