I would say 3 people have contributed significantly.
1) Indie dev - build a first version of the game in Unity. She is responsible for the look&feel of the gameplay
2) Fiver person 1 - who made the very crude js version of the player which I refactored into final version.
3) Fiver person 2 - who helped me with the design of the game menu.
Other than that I have hired some other designers on fiverr, whos designs I didn't end up using, several testers and reviewers.
I also asked all friends and family to try it out and I have observed if they can figure out what the game is about without any hints.
Nothing really unexpected happened in regards to working with people.
