Monument Valley 2
Gentle touch controls, no reflexes
Stick it to the Man!
Simple platforming with no twitch ceiling
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Monument Valley 2
Nothing opposes you
Stick it to the Man!
Mind-reading is a story device, not opponent modelling
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Monument Valley 2
Deterministic authored levels
Stick it to the Man!
Every gag and sticker puzzle is scripted

Monument Valley 2
Geometry manipulation puzzles with intended solutions
Stick it to the Man!
