This was so lovely! Mahiro (not to be mistaken with Milo!!!!) is a very endearing character and I really loved his relationship with Kyu (not to be mistaken with Q!!!!!).
Joke aside, I also really appreciated the commentary on heteronormative social norms and how, in the end, they just make people unhappy (both Mahiro and his father).
The GUI was also really great! And the illustration was lovely, I really love this fathering perspective you chose, it works very well with the story.
So, congrats on having created such a nice project in a week only!!! That's impressive!!!
