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 · Pure Mechanics
A precision-platforming metroidvania built around fluid traversal.

Execution · Pure Mechanics
Tetris with a puzzle mode - still a test of placement speed and stacking craft.
Ori and the Blind Forest leans Execution (Pure Mechanics); Tetris Plus leans Execution (Pure Mechanics).
Tetris Plus leans a little harder on execution, though the gap is small.
Ori and the Blind Forest
Precise platforming and bash-chain escape sequences
Tetris Plus
Piece placement speed under pressure decides everything
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Ori and the Blind Forest
Scripted enemies, no adaptive opponent
Tetris Plus
Versus mode adds only light opponent awareness
Tetris Plus leans a little harder on variance, though the gap is small.
Ori and the Blind Forest
Fixed layouts, minimal randomness
Tetris Plus
Random piece order is bounded and rapidly mappable
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Ori and the Blind Forest
Ability routing and shard builds matter
Tetris Plus
Puzzle-mode professor routes have known optimal solutions
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.
