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 · Twitch Chaos
The desert-set sequel to Alto's Adventure, adding balloons and wall rides to the endless ride.

Execution · Pure Mechanics
A percussive top-down rampage where a gorilla smashes through procedurally remixed levels.
Alto's Odyssey leans Execution (Twitch Chaos); Ape Out leans Execution (Pure Mechanics).
Ape Out leans a little harder on execution, though the gap is small.
Alto's Odyssey
Trick chains and wall-ride timing
Ape Out
Split-second grabs and throws under fire
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Alto's Odyssey
No opponents
Ape Out
Guards react predictably
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Alto's Odyssey
Procedural desert biomes vary each run
Ape Out
Procedurally shuffled layouts and enemy placements
Ape Out leans a little harder on optimization, though the gap is small.
Alto's Odyssey
Light goal and combo systems
Ape Out
Few systems beyond momentum and angles
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.
