This is my comment as a player.
1. I like the character selection. the character design is quite cute. I think if the artstyle can be improved, many children and girl player will like it.
2. Overall world is cute too. maybe can add bigger island or another island with different element on it.
3. The game mechanic is too simple and can be confusing.
4. It will be great if different character can do different thing. So, the game will be more interesting and player has more option to play repetitively.
5. A lot more need to be improved.
6. Hope can see a full developed game soon.
