This right here, this is the most exciting demo I've played for a long while. And there's a whole bunch of reasons for that!
Firstly, it hits my nostalgia gland pretty hard. The old school style and design instantly appeals to the kid in me that played way too much Harvest Moon on the Game Boy. And at the same time it has a very modern feel to it, an updated retro feel!
Next, everything just flows so nicely. You wake up, talk to a character, learn how to do a thing and then go and do the thing. Then you learn a new thing and do that, all the while picking up on other little things in between. In the space of the five days you can play in the demo I experienced so much, and I can only imagine how much more there is!
Also, the characters are instantly likable. I love everyone I've encountered so far (even if I did mercilessly rib most of them and denied one of them a bed). It's such a feelgood game, it really perked up my day just playing it!
Finally, the huge amounts of customization you can put out there to manipulate the landscape and make room for new buildings and eventually the farmland is mind-boggling. I can't wait to get more into that and will definitely, definitely be grabbing a copy of this when it comes out. I must get more people into Bumville!
Congrats on the success of the Kickstarter campaign, and be sure to take players' experiences and opinions to heart as you continue to develop the game, and after release too! Close communication with the community is really what makes good games great. Keep up the awesome work! =)
