Broughlikes are roguelikes which emphasise mechanical tightness and focus on singular mechanics of the roguelike genre. They feature small grids, have low randomness, and are extremely replayable. Broughlikes rarely if ever have wait commands as "attacking is already a form of waiting;" when waiting is an available command it consumes resources.

"Certain recurring stresses are characteristic of Brough's approach:
Small, square boards & small integers
Orthogonal 4-way movement
Parity & zugzwang (or "compulsion to move," i.e. inability to freely "pass" a turn)
Streamlined controls, e.g. attacking with the same input as movement
Roguelike mechanics like procedural level generation, permadeath, teleport, polymorph, etc.
Numerology, i.e. conspicuously consistent integers
"Glitch" mechanics / aesthetics
Identification & decryption
Positional tactics: pushing, pulling, choke points & egress
Differentiated resource binaries, e.g. credits & energy, blood & mana, etc.
Unconventional scoring systems
Idiosyncratic art & audio
Topologies, synchronies, overlapping matrices"

There are plenty of Broughlikes that are not in IGDB, such as:
Loopy Wizard
Arcane Tower
Marsh Adventure
Chesh
Saugzwang
Unit 4
Crab
Limonchik
Crypt of the Bone King
A Dreamless Hopeless Life Of Grave Robber
