Flow and Pacing

• Navigation Flow
• guide the player through the level
• lighting, combat, puzzles, collectables 
• pitfalls
• dead ends with no reward
• unclear buttons or levers
• not framing a view
• direction of opening doors
• open in the direction of the players progression
• monotone levels
• same assets repeated
• large flat planes as playing surfaces 
• lacking variety of enemies, predictability 
• Gameplay Flow
• Difficulty
• Should increase in difficulty as the player progresses through the level
• Learning new skills/mechanics
• Placement of Obstacles or Bosses/Mini Bosses
• Story Beats 
• too fast, too slow, too monotone?
