Sometimes in 2D games, we need to completely remove the shadows from the scene. Here is a simple way to do that.
Set the camera angle to whatever is needed for the game.
Set the light angle to the same angle as the camera.
But there might still be fuzzy shadow bleed at edges.
for a perfect shadow removal, we can move the camera very far from the scene. it is less convenient, but works perfectly.
For a top-down 2D game, we can set the camera Y value to a very high value.
here is an example using camera X=0 and Z=0,
Example: (you should use your appropriate camera X and Z values. Set The Y value to a very high value.)
For 3D games, using this method is tricky and involves some math, so we don't talk it here.
