What features does Planedrift offer while playing a text adventure?

Planedrift adds a small set of convenience features around classic Infocom interactive fiction: nice fonts and colours with light and dark themes, auto-saves and rewinds, a searchable transcript, and the ability to capture to-dos while you play. These apply while you're in a game — the site describes itself as a calm, unhurried, pick-up-and-put-down way to play, and the features are built around that idea rather than around changing the games themselves.

The features, and what each one does for you

Nice fonts and colours, with light and dark themes

The reading surface is styled rather than left as raw terminal text, and you can switch between a light and a dark theme. This matters most in a text adventure, where nearly all of your time is spent reading room descriptions and parser responses. If you play in the evening or in a dim room, the dark theme reduces glare; in daylight, the light theme may be easier on the eyes.

Auto-saves and rewinds

Planedrift saves your progress automatically, and you can rewind. For Infocom games this is a meaningful change: the original experience often punished a single bad move, and saving meant managing save files yourself. With auto-save plus rewind, you can step back from a dead end or an accidental death without restarting. The site also mentions resuming a previous game, which fits the pick-up-and-put-down framing — you can close the tab and come back later.

Searchable transcript

Everything the game has printed stays in a transcript you can search. In practice this is a memory aid: if a character mentioned a location twenty turns ago, or a puzzle hint scrolled past, you can search for the word instead of replaying. It also helps when you return to a game after a break and need to re-establish what you already know.

Capture to-dos while you play

You can note to-dos during play without leaving the game. Text adventures generate lots of small intentions — "come back with the lamp," "try opening the egg later" — and this keeps them in one place instead of on scrap paper.

How these fit together

What to keep in mind

These are player-comfort features; they don't alter the games' puzzles or difficulty. The site's own description of what it plays is specific: Zork I, II and III are offered directly, and you can bring your own story file ending in .z3. For more Infocom titles, the site points to the Obsessively Complete Infocom Catalog and recommends the Masterpieces of Infocom releases, which it says are the versions Planedrift is tested against. So if a feature like rewind is central to how you want to play, check that your game is a .z3 file from a release the site is tested against before relying on it.
