I tend to prefer VN's with some voice acting (just generally helps to keep me focused), but I could not ignore the beautiful art in this and I really loved it! The sprites and backgrounds were all very clean looking and gorgeous!! Very sweet story, and I went through different choices to see the different endings as well. I do agree with some of what UltraShiko said below about the writing needing a little more depth, but you guys still have so much other great things to show for a game made in a month! There are also a couple of minor grammatical errors as well, but not too bad.
I really appreciated the pop-up meanings of certain words during gameplay and also liked that I could go through and listen to the music tracks in the menu afterwards - they're so nice, so it was great to listen to them outside of playing!
Can't wait to see what else you guys make in the future - very promising talent all around <3
