"I Will Get Rid of Fun" — Jonathan Blow at IndieCade on Digging Up The Witness's Line Puzzles

Introduction

Today's Tsumiki roundup. One piece today.

Over the past few days I couldn't find a fresh puzzle-design discussion from a source I trust. So today I'm digging up an older one: Game Developer's (then Gamasutra) report on Jonathan Blow's IndieCade talk, published October 8, 2011. Original ↗

It's fifteen years old, but it hasn't aged. Five years before The Witness (review ↗) shipped, Blow explained in his own words how he found its line-drawing puzzles.

The talk took place at IndieCade in Culver City, California. It was co-presented with Miegakure's Marc ten Bosch under the title "Designing to Reveal the Nature of the Universe." The article is by Mathew Kumar. It focuses on Blow's remarks and doesn't describe ten Bosch's portion. Original ↗

The starting point was The Witness. Blow wanted a lush, explorable world with puzzles you'd recognize as puzzles at a glance. He settled on players drawing lines on in-world screens to register solutions.

The first problem was input. With freeform drawing, a mouse and an analog stick would make the same puzzle differently hard. So players could only draw in pre-determined grooves.

But as Blow put it: "Making it so you could only draw in pre-determined grooves was an early decision, but that still didn't pin down very much." There would be a clear place to start — but where does it end? Can the line cross itself? The questions kept coming.

Allowing crossings made things a visual mess that didn't please him. So he decided the line can't cross itself. That one decision opened an unexpected door.

"When the line can't cross itself, the puzzle becomes about correctly drawing a partition, and that's something that came from exploration, not from a top-down decision about what I wanted the puzzles to be." Interesting mechanics appeared, he said, before he even knew what any of the puzzles were.

From there the talk turned to completeness — thinking design decisions all the way through, beyond "fun." "I care about completeness a lot. I will take it past the point where some people think it's a good idea." And: "I don't agree that games have to be the most fun they can be; I will get rid of fun if it means I can get at something deeper or more complete."

His example was World 4 of Braid (review ↗), where running right moves time forward and running left rewinds it. Keys you pick up there are exempt from rewinding. That follows the player's expectation: if you pick up a key, you want to run right and left with it.

Blow kept even this exception consistent. Exempt keys glow green, like every other object immune to time manipulation. Then, at the end of the world, he placed a puzzle where the key is not exempt — something that "made sense" but could be "very difficult to work out for the player."

He called this kind of surprise — one that still works inside the game's systems — "very valuable." "Surprise is sort of the same thing as the information content of a message." A message that says only what you expected contains no information. He also pointed to the "Veni Vidi Vici" section of VVVVVV.

He closed on truth: to design a good puzzle, create a situation, examine what its "truth" is, and use that. "Even if I suck as a game developer, and the design is not good, then it will still be good in some way, because the truth is valuable."

Why it matters

What strikes me is that the heart of The Witness is described as a discovery, not an invention. The partition puzzles weren't the goal. They surfaced after a string of small decisions: input fairness, visual taste, and a ban on crossings.

This echoes Kizuki's piece on Blow's design philosophy on this site. Each time a rule is fixed, you ask "then what about this case?" I read that persistence itself as the engine that produces puzzles (that's my interpretation).

The Braid example is also practical for anyone making games: if you create an exception, give it a visual promise. Then break that exception once, on purpose, and the player is tested on whether they truly understood the rule.

Today's pick

"I will get rid of fun if it means I can get at something deeper or more complete."

— Jonathan Blow, IndieCade 2011 (as reported by Game Developer). Fun treated not as the goal but as one means among others. I think that resolve is what built that quiet, stubborn island.

Closing

I can't solve even a one-line puzzle, but reading about the moment the line was forbidden to cross itself, I felt I'd sat at the designer's desk for a minute. Maybe rules aren't made so much as dug up. Tomorrow I'll go looking for another design discussion somewhere in the world.
