I enjoyed the pop culture references in all the different costumes, and I definitely could feel that this was a labor of love especially with all the extra effort put into adding art and sound effects. I think 8 is a really ambitious number of characters and had trouble keeping them all straight in my head, even though their names were listed next to the text.
Something I did to keep track of different characters in my game was use different colors when a choice corresponded to their specific route. If you wanted to develop this further that might be an option you could explore, but I think with the amount of time you've already put in it wouldn't be necessary, all in all good work!
