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

Optimization · Pure Optimization
Charming diorama puzzler about routing a jumpless Toad to each star.

Optimization · Pure Optimization
Co-op physics puzzles solved by combining four characters' distinct powers.
Captain Toad: Treasure Tracker leans Optimization (Pure Optimization); Tiny Brains leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Captain Toad: Treasure Tracker
Gentle navigation, no jumping, light timing
Tiny Brains
Light physics handling, occasionally timed sections
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Captain Toad: Treasure Tracker
No adaptive opposition anywhere
Tiny Brains
No adversary - the puzzle is the opponent
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Captain Toad: Treasure Tracker
Everything is visible and fixed
Tiny Brains
Puzzle rooms are fixed once seen
Captain Toad: Treasure Tracker leans a little harder on optimization, though the gap is small.
Captain Toad: Treasure Tracker
Rotating dioramas to solve fixed route puzzles
Tiny Brains
Combining four powers into solutions is the whole test
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.
