I just finished the game (got 2 different endings, and will replay later for the others) and really enjoyed it! The storyline was sweet, and it was nice watching the characters develop. I also really enjoyed the ending scenes and the fact that we have a gallery now!
I've also played the first game (Summer in Fairbrook) and really enjoyed how you updated it. The writing was just as good, but I enjoyed exploring the game from a girl's perspective. Some of the things that were updated and I REALLY enjoyed:
1) more cutscenes/images for each character! Those were adorable!
2) More included hints/tips for getting different endings
3) The gallery feature! This was one of my biggest regrets from the first game; being unable to look at the CGs I collected!
All in all, this was a very welcome addition to my game collection. It played like the first game, in terms of charm, but with more development and polish added.
