To begin with, I wouldn't say I like the rubric with scores from 0 to 4. Because you could do 1 to 5 and even if I write a poor response at least I will not get a 0. This is very important for my self-esteem. I don't want to get a 0 in any video game because I can never imagine myself losing.
Also, I would say that the game is trying to gatekeep non-English speakers because everything is in English and the players need to comment in English. So one way to improve is definitely to add a link to Google Translate in your game so people from different cultural backgrounds can at least try to enjoy the game.
However, I am an Irasutoya head so I have to give 10/10 to every single game using Irasutoya assets. So the game is fine. Definitely will recommend it to my friends and family if the game is available in 200 languages.
