Patch Quest

Beat the level by editing the level itself: flip the unlocked rules until the unit test goes green and the exit opens.

How to play

Every level is a tiny grid driven by a config file. Most lines are locked, but a few are editable — toggle a flag, nudge a number, or remove a wall. A goal expressed as a unit test turns green the instant your patch makes the exit reachable.

• Edit only the unlocked config lines to change how the level behaves
• Watch the grid's reachable cells and the test bar update live as you tweak
• Solve with the fewest edits and the least time for a higher score

Controls

• Desktop: click toggles and +/- steppers on the unlocked config lines
• Phone & tablet: every edit is an on-screen tap

Game modes

• Daily: the same multi-level run for everyone today
• Practice: a fresh randomized run each time

Tips & strategy

• Read the goal's plain-English line first — it tells you exactly which property must become true
• Fewer edits scores more, so look for the single rule that unlocks the path instead of changing everything
