Level design is the process of creating the environments and stages in video games. It involves planning the layout, challenges, and objectives that players will encounter. Designers consider factors like player movement, pacing, and the overall experience to ensure that each level is engaging and fun. Good level design balances difficulty and accessibility, allowing players to progress without frustration. It often includes elements like obstacles, enemies, and puzzles that encourage exploration and strategy. Effective level design can significantly enhance a game's enjoyment and replayability, making it a crucial aspect of game development.
