Thank you so much for this game and the translation! I had a fun time reading it. The art and music are lovely. Even though the overall game is not long, Kei's best ending and Chihaya's entire route were really emotional ;w; I enjoyed trying to unlock everything, and I appreciate that you put hints in game as well, it made it easy to backtrack!
That said, I do have some feedback about a some things I ran into while playing. Spoiler warning just in case:

While trying to get Chihaya's Ending 5 using the "happy" -> "ask" -> "continue" -> "accept" -> "return" choice path, the entire scene back at MC and Chihaya's home was still in Japanese for me (I'm playing in English on Windows 10). I remember there was also a single untranslated line in Kei's best ending (when MC was about to enter the theater).
