We're so happy you enjoyed the game (and we're so touched that you replayed it!! It brings so much joy to our hearts) <3
Regarding the bug, thank you so much for bringing it to our attention, we'll have a look and make the necessary changes before the next release! As for the other characters' achievements, you'll have to get them when their routes are out- we're sorry about that!
We're so glad that you liked the characters and the art, we'll do our best to keep it up in the next instalments~ thank you for your kind comments on all of them hehe (ps don't worry, there will be more of Miles and Jun and Faye in the other routes too~) (pps your idea about including Maya's little brother is very intriguing! Stay tuned for more perhaps)!
