Black Cat Book Club is an idle cozy game built around a small set of verbs: read a tome, earn Focus, decode a glyph, learn a spell, and unlock the next tier of library. Reading is mostly idle, with upgrades like Memory, Comprehension, and Reading Speed letting the cat progress faster on harder tomes over time.
The core idle loop
Your cat selects a tome, devotes Focus to it, and reads over time. As the cat reads, it accumulates comprehension progress and produces decoded glyphs that feed back into the focus economy. New tomes unlock spell schools — sigils, summoning seals, alchemy, and astral magic — and each spell school opens new customisation and progression paths.
Upgrade types
Three upgrade families show up in the Steam store description: Memory lets the cat retain more from each tome, Comprehension lets it process harder tomes, and Reading Speed determines how quickly it works through a tome. Together they govern how fast the library grows and how quickly spell unlocks open up.
The Focus economy
Focus is the shared pool of attention the cat draws on while reading. The cat regenerates Focus between sessions and can be replenished by some customisation items. Players manage Focus by pacing tomes and resting the cat so upgrades compound rather than burning through the pool.
