Why do some puzzles feel impossible until they're obvious?
The feeling of puzzles being impossible until they become obvious is due to the Einstellung Effect, a mental block caused by past experiences. Game designers intentionally create these 'perspective shifts' to challenge players. For example, the game 'Portal' used momentum puzzles that required players to unlearn their assumptions about gravity. If you're stuck on a puzzle, try sleeping on it, explaining the problem aloud, or attempting to solve it backwards. These strategies can significantly improve your solve rate.
