head to head
Downwell asks more than Montaro : RE, and the gap is optimization.

Execution · Pure Mechanics
A frantic vertical roguelite about falling fast and shooting your boots.

Execution · Pure Mechanics
A comedic reflex platformer testing jump timing against fast obstacles.
Downwell leans Execution (Pure Mechanics); Montaro : RE leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Downwell
Gunboot timing and split-second landings decide runs
Montaro : RE
Reflex jumping and timing carry this runner-platformer
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Downwell
Enemies never adapt
Montaro : RE
No adaptive opponent in a solo arcade game
Downwell leans a little harder on variance, though the gap is small.
Downwell
Procedural wells and shop offers vary runs
Montaro : RE
Some procedural obstacles add randomness
Downwell leans clearly harder on optimization.
Downwell
Combo lines and upgrade picks reward study
Montaro : RE
Little to solve beyond reacting to obstacles
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.
