I, like previous commenter, liked the background music very much :) Regarding the text and ui, I think the viewport size maybe got messed up somewhere along the way during export and setting it in itch or something? Sometimes parts (smaller or bigger) of ui elements were also cut partially of screen, some "folders" with those information like "do you like tea?" were like 100x too big, and sometimes text scaling was making it hard to know which is "+" and which is "-" (see screenshot). But the whole idea was good, a nice collection of science and math mini-games. I tried it for 3 times, each time got caught, although each time after longer time (not sure if there is some winning condition and I just suck, or the goal is just to go for as long as possible). 
Regarding your code question, you could e.g. get rid of listx array and instead of "for i in listx" use "for i in range(1, 8)" ;)
