Man, the demo was cute, both art-style wise and character wise. Amie's so adorable, when she was near tears, I wanted to wring Kennykens by the neck :)
As for the guys, I'd say I like Hisashi the most. He was pretty nice, but what has me interested in him is how much he smiles. 18 smiles, huh? Literally can't tell what the guy's thinking. Also, his fish clip is pretty cool.
Kennith's a jerk, but it's not like he was rude to Amie for no reason. Personally, I'm curious as to why he can't be at Heartful Flowers all the time, and why he doesn't like phones.
As for Ross, he seemed sweet, and he definitely knows what Heartful Flowers' secret is (I think) but we didn't see too much of him, so I don't have too many comments.
I liked the phone feature, and I really love the aesthetic of the game. I always found terrariums to be pretty, and I think this is the first time I've seen a game incorporate them as elements.
Overall, great job! I can't wait for the updated demo!
