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

Execution · Practiced Mastery
Aiming banked bubble shots quickly while planning chain clears.

Execution · Practiced Mastery
A gothic horror FPS where a paranormal investigator fights a family curse with revolver in one hand and spells in the other.
Bust-a-Move 4 leans Execution (Practiced Mastery); Clive Barker's Undying leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Bust-a-Move 4
Precise bubble aiming and bank shots under time pressure
Clive Barker's Undying
Dual-wielding spells and guns under pressure
Bust-a-Move 4 leans a little harder on reads, though the gap is small.
Bust-a-Move 4
Versus mode allows mild human pressure timing
Clive Barker's Undying
Horrors follow scripted patterns despite feeling malevolent
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Bust-a-Move 4
Bubble colour feed is random but bounded
Clive Barker's Undying
First-run scares and unknown manor secrets hide information
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Bust-a-Move 4
Clearing patterns and pulley setups have known solutions
Clive Barker's Undying
Spell upgrades and Scrye-revealed puzzles reward system mastery
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.
