head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Execution · Pure Mechanics
A pure paddle-precision breakout test with nothing hidden beneath.

Execution · Pure Mechanics
A remastered classic platformer where mastering the cane-bounce mechanic carries every level.
Alleyway leans Execution (Pure Mechanics); DuckTales: Remastered leans Execution (Pure Mechanics).
Alleyway leans a little harder on execution, though the gap is small.
Alleyway
Paddle precision and angle control decide every screen
DuckTales: Remastered
precise cane-bounce platforming required
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Alleyway
Bricks cannot fight back
DuckTales: Remastered
scripted enemies, no adaptation
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Alleyway
Ball physics are deterministic with minor bounce uncertainty
DuckTales: Remastered
minimal randomness
DuckTales: Remastered leans a little harder on optimization, though the gap is small.
Alleyway
Brick-clearing order barely matters beyond basics
DuckTales: Remastered
level routes lightly solvable
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
