Ideas for a new RPG game #1 (FEEDBACK WELCOME)

So we've been getting lots of ideas for an RPG game recently, and while often times we regret sharing ideas as after it's out there it sometimes ruins our motivation, we're already low on motivation. There's nowhere to go but up on this, haha. We'd love any feedback you have for us, feel free to comment something supportive or something telling us how stupid and unoriginal the ideas are.

Inside a room, there is a box.

Inside that box, there's a world.

Inside that world, there's a room.

Inside that room, there's a girl.

In this game, you meet and play as a little cow girl and all her friends in a big, open sea world. You sail around on a bedroom island, searching for friends. More often than not you find trouble, as it seems the whole world outside of your little bedroom island is hostile towards you, but the cast is determined that there must be more friends out there.

The main crew!

• Mumi - An outgoing and caring cow girl! She wants to make everyone else around her happy! She's set on making as many friends as she can, and is leading the search!
• Haru - A silly but shy shark kid! They are quiet most of the time, and it can be difficult to tell whether they're making an intentional joke or not.
• Tilomu - A smart and irritable pigeon man!! He's not one to mess around, and often gets into squabbles with the others. Has a soft spot for bread.
• Samasa - A timid and clumsy goat girl! She's a bit stubborn, and has a bad habit of munching on anything and everything around her. Struggles with listening to others.

Some side characters!

• The King - In their travels they find many islands are under the rule of the King! Cold and calculating, he doesn't care much for Mumi's quest for friends and would prefer they work to expand his kingdom. Claims control over all the islands in the sea.
• The Queen - Many more islands are under the rule of the Queen. She almost never shows her face to the world, preferring to lock herself away in her castle and have her Head of the Guard run most things in her queendom under her guide.
• Jochi - The leader of a rebellious group of pirates, sailing the sea and looting islands! Has some radical ideas and offers lots of friendship at a price!
  

We're going to end this blog entry here, and hopefully make more talking about ideas for the setting and gameplay. Please leave any feedback you have, we'd love to hear your thoughts on anything. We know this is a very shallow look at these characters and the most basic look into the world so far, sorry. The ideas are still formulating.
