Using alphas, betas, and previews to gather complaints isn't a new strategy by any means in the gaming field, but a developer responding to them is rarer. The developer behind Lords of the Fallen has actually made a video responding to recent criticisms from players going through the game in the preview build. In the video he talks about:

• Difficulty
• Spell trees
• New game+
• The PC experience
• Length of the game
• Light gear vs. heavy gear
• Non-linear exploration
• Timing and combos
• Movement and attack speed
• Using spells vs. using gauntlets
• The story, audio logs, and item descriptions
