A Diablo-like roguelike for the terminal.
Every torch, campfire, crystal, lava pool and spell casts real, colored, flickering light.
You see only what the light reaches.

Nothing to install:

ssh medv.io -p 2222

Or run it locally:

go run github.com/antonmedv/termablo@latest

Add -seed 42 and the world is the same every time. Share the seed, race a friend.

docker compose up -d        # then: ssh localhost -p 2222

or, without Docker:

go run github.com/antonmedv/termablo@latest -ssh :2222

Built with Bubble Tea and Wish.

Nobody tuned the numbers by hand. Two scripted players, a fighter and a caster, play the game to the end over many seeds. How deep they get, what kills them and what their gold does is held against a set of goals (internal/balance), and every number in the game's formulas is a knob (rules.go) a balance pass may turn.

make knobs                                  # every knob: value, range, meaning
make eval OUT=balance/runs/a.json SEEDS=96  # both builds over 96 seeds, scored
make eval OUT=balance/runs/b.json SEEDS=96 RULES=try.json   # knobs laid over the defaults
go run ./cmd/balance compare balance/runs/a.json balance/runs/b.json
go run . -bot fighter -seed 7               # watch one run

A rules file is a JSON overlay, {"WakeRange": 12}. The score is the weighted distance outside the goals, lower is better; compare pairs the two runs by seed and says whether the difference is noise. Every decision goes in balance/LEDGER.md, every pass ends in balance/REPORT.md. In Claude Code, /balance runs the whole loop; the runbook is docs/balancing.md.
