You cannot legally use famous characters in games like that, it is forbidden in most game jams and is illegal in general, commercial game or not.

There’s no sound. Menu is atrocious, I’m sorry but it is true. It is better to have single color buttons than whatever picture you used there, especially considering it is Unreal Engine game that isn’t made on purpose to look as old graphics.

For a child, the point of view is too high, room seems to small and should seem too big instead (you’re a child alone in a regular house, right?)

I liked the Spooky space dimension and how the walls there disappear visually was interesting.

In games for interaction E is more used than Enter.
