Congratulations on finishing your first KN! Haircuts was good! Simple, short, and sweet.
You’ve got a nice writing style, but there were a few typos in the game, so maybe next time ask someone to proofread your work. There’s always plenty of people here on the forums who’d love to help you out, so don’t be afraid to ask!
The music worked well with the story, especially when it changed after Samantha’s words. But I'd change the track again at the end, if I were you, since staying with the same sad, dramatic music for the rest of the story made the ending feel sad rather than happy.
The photo BGs were good too! But I would have really loved to have seen the inside of the barbershop when the main character entered, since seeing the outside while the main character got his haircut felt a little odd. But I know finding resources is hard, and it worked the way it did, but just a small suggestion to help immerse the player a bit more.
Overall, good job! Hope to see more games from you soon!
