Duck Souls+ (2018) is a roguelike platformer where a duck navigates procedurally generated levels packed with spikes and obstacles.
It lasts about 1 hour for a full playthrough with high replayability, and reviewers generally liked its precise controls and brutal challenge.

• I needed more than five times as long as the average player to beat that game
• another game was completed on the same day, too
• intense sessions: I played more than 4 hours a day
