I know that there is not really any need for a physics engine to achieve this but I want the functionalities of detecting collisions so it is necessary for the purpose of the game.

But you can use inbuilt physics engine just for collision detection. Use setCollisionBitmask, setCategoryBitmask & setContactTestBitmask properly
You can search this forum for such post.
