I've only played through one route so far (Lyell's).
The art and story are cute,
but you desperately need an editor.
There are just so many misspellings, grammatical errors and awkward phrasings that would be much better with minimal tweaking.
They made an otherwise nice story difficult to read.
There are plenty of people who will stop reading something if there are too many errors like this. (I know, because I tend to be one of them.) So I genuinely think that you would be giving more people the opportunity to enjoy your stories if you found someone to do even minor editing work on the game. (Fixing the uses of 'their' when it should be 'they're', for example)
I'd like to reiterate that I enjoyed the story itself, so I hope I'm not coming off as critical just for the sake of putting down those who put hard work into the game.
