Myth: Playtests Are For Polish. Your Core Loop Begs to Differ.

Playtests: Not Just for Shine

Many developers believe playtesting is a final step, a way to buff and polish a near-finished game. That’s a dangerous misconception, especially for indie devs.

The Core Loop: Your Game’s DNA

The core loop is the heartbeat of your game. It’s the fundamental action the player repeats, and it’s what keeps them engaged. Think of it as “Do X, get Y, use Y to do X better.”

Is that loop satisfying? Addictive? Or confusing and dull? You need to know early, and you can’t rely on your own biased perspective.

Early Playtests: Core Loop Validation

The biggest mistake I see is delaying playtests until the art is polished and all the features are implemented. You’re essentially betting everything on a hunch.

Early playtests aren’t about finding bugs or tweaking UI. They’re about validating (or invalidating) your core loop.

They’re about observing players interacting with the most basic version of your game. Can they grasp the core mechanic? Are they getting any enjoyment from it?

Think of Hades. Supergiant Games didn’t wait until all the gods were voiced and the art was complete. They iterated on the core combat, death, and upgrade loop relentlessly early on.

Structuring Core Loop Playtests

Focus is crucial. Design your early playtests around specific questions:

• Does the player understand the goal?
• Is the feedback from their actions clear?
• Do they feel a sense of progression or accomplishment?

Don’t ask leading questions. Instead, observe.

Give the player a minimal tutorial (if necessary) and then let them play. Take notes on their actions, their expressions, and their verbal reactions.

A simple question like, “What are you trying to do right now?” can reveal massive misunderstandings.

Interpreting Lo-Fi Feedback

You don’t need fancy graphics to get valuable feedback. In fact, minimalist visuals can be an asset.

They force players to focus on the mechanics themselves, not the shiny art.

Pay close attention to player frustration. Are they getting stuck? Are they abandoning the intended path? Are they getting bored?

Don’t dismiss these early signs. They are flags indicating a core loop problem.

One of my earliest projects was a rogue-lite space shooter with placeholder art. Players consistently struggled to understand how their weapon upgrades worked. It wasn’t a bug; the system itself was flawed. We completely redesigned it based on that early feedback.

Iterating on the Core Loop

Playtest data is worthless without action. Don’t get defensive; embrace the feedback.

Identify the core loop elements that are failing and brainstorm solutions. Don’t be afraid to make radical changes.

Iterate quickly. Implement a change, playtest again, repeat. The faster you iterate, the sooner you’ll find a satisfying core loop.

Look at Celeste. The core mechanic of climbing and dashing was refined through countless iterations, informed by playtester feedback. The result? A platformer with incredibly tight and responsive controls.

Avoiding Common Mistakes

• Ignoring Negative Feedback: Confirmation bias is a killer. Listen to the players who are struggling, even if others are enjoying the game.
• Over-Explaining: Let the game teach the player. If they can’t figure it out on their own, the design is probably flawed.
• Focusing on Minor Issues: Don’t get bogged down in tweaking UI elements when the fundamental gameplay is broken.
• Testing with Friends Only: Your friends are likely to be too forgiving. Get feedback from strangers.
• Treating Playtests as Optional: Make them a core part of your development process.

Case Study: Dead Cells

Dead Cells is a masterclass in core loop refinement. Motion Twin ran extensive alpha playtests, constantly tweaking the combat, progression, and level design.

They listened closely to player feedback, even when it was harsh. They weren’t afraid to make major changes to the game based on what they learned.

The result? A rogue-lite that’s both challenging and addictive, with a core loop that keeps players coming back for more.

Your Core Loop’s Potential

Playtesting is not just for polishing a finished product. It is a discovery process.

Use playtests to uncover the hidden potential of your core loop. Find out what your players want to do and make it satisfying and intuitive.

Start early, listen carefully, and iterate relentlessly. Your game will thank you for it.
