head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Pure Mechanics
A rhythm racer that turns any music file into a reflex puzzle track.
Execution · Pure Mechanics
Classic arcade aim-and-timing against escalating scripted waves.
Audiosurf leans Execution (Pure Mechanics); Pooyan leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Audiosurf
Lane-switching to the beat tests reaction speed.
Pooyan
Shooting wolves on balloons is pure timing and aim
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Audiosurf
No opponent.
Pooyan
Wolves follow simple fixed behaviours
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Audiosurf
Track generated from song, then fixed.
Pooyan
Wave spawns vary slightly but are quickly learnt
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Audiosurf
Block-matching color strategy learnable per song.
Pooyan
Scoring patterns and wave order can be memorised
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.
