I am currently following a tutorial to make Pacman in Unity. I was told to use 2d colliders around the little blocks that Pacman goes around. I've accidentally put the colliders on the main camera and not the maze sprite.

Will this affect my game in any way? Or do I need to put the colliders on the sprite? If I do is there any quick way to redo my colliders?

Any help is greatly appreciated.

Here is the link to the tutorial: https://noobtuts.com/unity/2d-pacman-game

I am happy to provide screenshots if necessary.
