Thats our bad if the tutorial didnt explain it well enough
You got it right by thinking to click on the folder, just try to meet the minimum defense score using stuff from the store and the resources you have, then once you're satisfied with what you've done for the day, click on the folder and choose the answer you think suits the given situation best
After that, use the bed to progress, dont worry about a timer, you have unlimited time so you can think about what you're doing before you progress
As for the folder being weird to click, it should highlight itself when your cursor is over it, though ill admit, the glow is feint and we couldve done a bit better with signposting it
Regardless, even if you dont try the game again, thank you for your thoughts and feedback
