and possible dealbreakers

Uses Unity, a leading engine in the game development industry, which allows learners to build games for multiple platforms, including mobile and PC

Covers object pooling, which is an important optimization technique for improving game performance by reusing objects instead of constantly creating and destroying them

Explores the Singleton pattern, which is a fundamental design pattern used to manage unique instances and facilitate communication between different parts of the game

Employs Scriptable Objects, which are data containers that can store large quantities of shared data independent from class instances, making it easier to manage game data

Requires Unity, which may necessitate learners to acquire the software and familiarize themselves with its interface before starting the course

Focuses on creating a 2D game, which may not appeal to learners interested in developing 3D games or those seeking to expand their skills in 3D game development
