Is this 3D model good or is it too simple?
Detached hands and feet are easier to animate, but I want it to look good.

I have an idea for a new Amelia fangame. Tell me if it's a good or bad idea.

Starts with a simple cutscene:
Beeg Ame: "Smol Ame, are messing with my time travel stuff again?"
Smol Ame: "Maybe..."
Beeg Ame: "That's it! You are grounded!"
Smol Ame "Only if you catch me!"
They both go into a time travel portal.
Then it's 3D infinite runner game similar to Subway Surfers. Every 2 minutes or so they go into another portal and and the scenario changes.
You control Smol Ame dogding obstacles and if you hit too many of them, Beeg Ame catches you and are grounded.
Gif related would be the game visual style.

Is this a good game idea?
