Ajar and Rebound

Ajar went first, because you can't keep a player who never got in.

"Your first job — mine — you nailed," Ajar said, patting her burrow's many entrances. "You opened doors. A speed slider, remapped controls, colorblind mode, subtitles — every one of those is a new way in, a new kind of player who can now reach your game. Players who'd have been locked out before are getting in now. That's real, and it matters, and most designers never even do it." She tilted her head. "But here's the thing about a door. A door gets someone inside. It doesn't decide whether they stay." She looked at Rue. "You can have the most welcoming entrance in the world — a dozen doors, every size and shape — and if the room behind the door is unkind, people will walk right back out the way they came. Getting them in is my half. What happens to them once they're in — whether the game is gentle when they stumble, or brutal — that's hers." She glanced at Rebound. "You opened every door and then, I'd bet, put something harsh just inside them."

Rebound took over, bouncing, because a player driven out was still lost, no matter how welcoming the door.

"Let me guess what's just inside your lovely open doors," Rebound said. "A player gets in — great — hits the first hard part, fails, and... what does it cost them?"

Rue winced. "A lot, honestly. They go way back. It takes a while to get another try."

"There it is," Rebound said, landing softly. "You welcomed them in through a dozen doors — and then the very first stumble punished them so hard they left. All your open doors, undone by an unkind room." She hopped. "Because a new player, or a player who got in through the speed-slider door because they needed things gentler — those are exactly the players most likely to stumble early. And if stumbling costs them a half hour and a wall of frustration, they don't feel welcome anymore. They feel shoved back out." She bounced. "My half is making failure cheap — soft landings, frequent checkpoints, instant retries, so a player who falls just bounces back and tries again, no big deal. That's how you keep the player the door let in. You welcomed them; now don't drive them off the moment they trip." She looked at Ajar. "Your doors get them in. My soft landings let them stay."

And then, together, they showed Rue the whole shape of keeping a player.

"So keeping a player who wanted to play takes two moves," said Ajar, "and you'd only made one. Welcome them in — open enough doors that different players can reach your game. That's mine." She patted her burrow. "Don't drive them out — make failure kind enough that a stumble doesn't shove them back through the door they came in. That's hers." She and Rebound stood on either side of Rue's game.

"And separately, each one alone leaks players," said Rebound. "All your open doors —"

"— are wasted if the room behind them is cruel; they come in and leave," said Ajar.

"— and all my soft landings —"

"— can't help a player who could never get in the door in the first place," said Rebound. "Kind failure behind one narrow entrance still locks most people out. And a dozen doors into a punishing room still drives them right back out." She bounced. "But together — welcome them in, and then be gentle when they stumble — and you keep the player. Every kind of player who wanted to play gets in the door and gets to stay past their first fall. That's not two features. It's two halves of one promise: you're welcome here, and I won't push you out for tripping."

Rue looked at his many-doored, harshly-punishing game and finally saw the leak. "So the doors got them in," he said slowly, "and the cruel failure sent them right back out. I did the welcoming and then undid it with the punishing."

"Now you see the whole of it," said Ajar and Rebound together.
