I've seen that many of the user created games have failed, but I plan to help anyone who wants to make a smaller game than those failed ones.

I don't know how to do code and stuff, but I am wondering if anyone wants to make it.
The following is just an idea of how the game wouldn't fail.

Coasters:

Steel
Wooden

Flat Rides:

Merry Go Round
Ferris Wheel

Stalls:

McDonalds
Burger King

Paths:

Concrete
Tile

Have you played Scream Machines?

No, I haven't

Go play it.

What is it? Do you have a link?
