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 · Practiced Mastery
A grim 2D action metroidvania steeped in religious horror.

Execution · Practiced Mastery
Dodging scripted bullet patterns while solving each fight's pacifist logic.
Blasphemous leans Execution (Practiced Mastery); Deltarune leans Execution (Practiced Mastery).
Blasphemous leans a little harder on execution, though the gap is small.
Blasphemous
Punishing 2D combat and platforming
Deltarune
Bullet-hell dodging in battles demands real reflexes
Blasphemous leans a little harder on reads, though the gap is small.
Blasphemous
Scripted bosses
Deltarune
Enemy patterns are charming but fully scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Blasphemous
Static world
Deltarune
Encounters and secrets are fixed once known
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Blasphemous
Rosary bead builds and routing
Deltarune
ACT routes, sparing logic and TP economy are solvable
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.
