Somehow, we're already getting close to the end of October. And yes, you know what I'm about to say: Halloween!

As a kid, one of my favorite things was going around the neighborhood collecting candy. Trick or treat! Growing up has mostly meant switching sides: now I'm the one handing out the candy. Thankfully, I can still dress up. Last year, I went as a witch to a costume party organized by a colleague, and this year's invitation has just arrived.

Which brings me to the usual problem: what should I wear this time?

I'm very good at getting stuck between too many options. So instead of asking for one costume suggestion, why not make a little game that helps me choose? Better yet, something other people can play too.

That's how I ended up making Trick or Fit?, a Halloween costume quiz with Cheso.

You answer 12 slightly ridiculous questions, and the quiz matches you with a Halloween alter ego—complete with costume ideas and a playful personality roast. Nothing scientific, just a fun way to let the questions pick your outfit.

Before we get into how I made it, here's a quick peek at the game.

That’s the finished game. Now, let’s walk through how I built it with Cheso, starting with a simple idea.

First, let's brainstorm

Before making anything, let's give the game a rough shape. I know coming up with an idea can be the hardest part, so I started by explaining the situation to Cheso:

Every Halloween, I struggle to decide what to dress up as. So this year, I want to create a fun little game that helps people choose their Halloween costumes before Halloween arrives. Do you have any ideas?

Hey, look at that! Cheso suggested an MBTI-style personality quiz that recommends a costume based on your answers. Not a serious personality assessment—just a playful way to find your Halloween vibe.

Instead of browsing a costume catalog, you answer questions about your preferences and little everyday reactions. Do you like being in the spotlight? Would you rather look sweet or sinister? Are you up for crafting an elaborate outfit, or would you prefer something you can put together from your closet?

The idea is to make the recommendation feel like you, not just another item on a list.

Honestly, that sounded perfect. I could stop agonizing over the options and let the questions do the choosing. Let's make it!

Let's turn it into an HTML webpage

Once the idea was clear, I asked Cheso to start building:

Sure, let's get started! Based on what we've just discussed, please create an HTML webpage for me.

An HTML webpage suited this idea nicely: players could choose their answers and work toward a result, rather than just read a static list of suggestions.

Cheso also has image-generation capabilities, so costume illustrations and Halloween-themed details can be created within the same workflow. That makes it easier to give the game its own look without separately hunting down every visual asset.

In my session, the first version was ready in under ten minutes. The basic idea was already there: answer the questions, get a costume recommendation. Exactly what I had in mind!

But a working first version isn't necessarily the final version. Now comes the fun part: making it feel more like the game I want.

A few tweaks, and a lot more Halloween

The initial mostly black design felt a little too plain. What about deep purple instead? Something moody, but still playful.

I also wanted to refine the questions. A costume quiz is more entertaining when the answers reveal a little personality, rather than ask you to choose the outfit you already like.

These changes don't need a long specification. A request could be as simple as:

Let's change the background to deep purple and refine the questions with more playful, everyday situations.

Describe what you'd like to change, then check the next version. The same goes for the wording, the visual style, or how the results are presented.

Now the questions include things like being asked to share a fun fact about yourself, or having someone steal a french fry from your plate. Small situations, surprisingly revealing answers—and a lot more fun than scrolling through costumes.

I mean, “I steal one back and call it even” is a perfectly reasonable response, isn't it?

Oh, wait. One last question...

Just when I thought I was finished, the game gave me one final Halloween dilemma:

At midnight, Halloween grants you one very suspicious opportunity. You choose...

Signing a contract with a demon? Claiming a haunted castle? Tempting. But putting every ghost into one chaotic group chat sounds like an excellent idea.

Surely nothing could go wrong there.

And the verdict is... Pumpkin Punk!

Okay, let's see the result.

PUMPKIN PUNK.

“Unapologetic, witty, inventive.” Hey, that's me!

The result isn't just a name. It gives me an outfit to work with: a black leather-look biker jacket, orange plaid trousers, studded combat boots, and a jack-o'-lantern helmet. Subtle? Not especially. Halloween-appropriate? Absolutely.

That's settled, then. I'm going as Pumpkin Punk this year. You can use your own result as a starting point too, adapting the outfit to whatever you already have or feel like making.

Your turn

If you're also wondering what to wear for Halloween, play the costume quiz here. I'm curious which result you'll get—and whether you'll immediately think, “Yep, that's me.”

And if you'd rather make a game of your own, try starting with a small idea in Cheso. Brainstorm the concept, turn it into a webpage, then adjust the questions and design until it feels right. That's the part I enjoyed most: I didn't need to have the whole thing figured out before getting started.

Now I just need to figure out the real-life pumpkin helmet.
