When I saw the coverof the game I thought "So cute, I need to play this". The whole art of the game is so beautiful! I keep watching the game images' while playing and thinking how much work did that take. The style is awesome.
And the story was beautifully sad for both characters. I think Polaris' story it's my favourite and I love (SPOILER ALERT) Eather, although he barely apears (END OF SPOILER). And, even though the true end it's kind of sad, It's my favourite.
So, congratulations, this is a good work and I've enjoyed it a lot!
