Play testing is a part of planning game polishing. Play testing is carried out after the game has been made according to the initial design. It basically reveals the entire user behavior throughout the game.
Here are the fields of exploration during play testing:
User gameplay difficulty level
User actions during gameplay
User actions while browsing the game
Whether the user is paying or not
Whether the game is running smoothly
Whether the user can adopt the gameplay
User retention
Play testing is planned on a limited group of targeted users. Often, developers release beta versions of the game in a certain region to carry out play testing.
