Eron is a precision platformer developed by a single developer that aims to be as challenging as Super Meat Boy. While the gameplay concept is simple - traversing levels by shifting between parallel realms to avoid obstacles - the execution is extremely difficult and frantic. The game has some positives like its artistic style and satisfying gameplay once mastered. However, it lacks clear explanations, has frustrating keyboard controls, and artificially increases difficulty through mechanics like a run button. Overall, the reviewer finds the game competent but in need of more polish and balance to be worth most players' time.
