(Sorry for the late reply!)
Thank you so much!! I do plan to do more with the story later on, but it probably won't be until after I do some more work on my other games.
So normally, going to different places on the weekdays doesn't change the plot, but the choices on days 4 and 5 will change the ending dialogue a little. (For example, the pregnant lady on day 4 tells the player that BedBug can't hurt them, and on night 5 the player will mention it to BedBug.)
Glad you liked it! (Your English is great by the way!)
