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 · Practiced Mastery
A Space Invaders descendant testing arcade aim plus an upgrade-economy layer.

Execution · Practiced Mastery
A pinball-platformer hybrid where flippers fling a mail-delivering beetle across an open island.
Titan Attacks! leans Execution (Practiced Mastery); Yoku's Island Express leans Execution (Practiced Mastery).
Titan Attacks! leans a little harder on execution, though the gap is small.
Titan Attacks!
Dodging fire while sniping descending waves is pure arcade aim
Yoku's Island Express
Pinball flipper timing drives all traversal
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Titan Attacks!
Alien waves follow fixed formations
Yoku's Island Express
Solo, nothing models you
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Titan Attacks!
Bounty drops and saucer timing add minor noise
Yoku's Island Express
Ball physics adds small bounce unpredictability
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Titan Attacks!
Upgrade purchases between waves form a small economy to solve
Yoku's Island Express
Learning table layouts and exploration routes
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.
