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.

Optimization · Practiced Mastery
A chaotic co-op action game where wizards combine eight elements into thousands of spells, often frying each other.

Optimization · Practiced Mastery
A hybrid testing maze-planning optimization backed by twitch shooting between waves.
Magicka leans Optimization (Practiced Mastery); X-Morph: Defense leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Magicka
Typing element combos quickly mid-combat is the hands test
X-Morph: Defense
Piloting the fighter through waves demands twitch dodging and aim
Magicka leans a little harder on reads, though the gap is small.
Magicka
Enemies are scripted; friendly fire isn't adaptive
X-Morph: Defense
Enemy waves are scripted - nothing adapts to your maze
Magicka leans a little harder on variance, though the gap is small.
Magicka
Co-op friendly-fire chaos adds unpredictability
X-Morph: Defense
Wave compositions are known and repeatable per level
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Magicka
Discovering and exploiting spell combinations dominates
X-Morph: Defense
Tower placement and maze routing decide whether waves break
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.
