What email address should I use to send you an invite?

Great idea, I hope to implement a dark mode. I don’t use it myself, but if there is a request, why not?
Core_Dev··on Show HN: I built a text-based business simulator to replace video courses
Thanks for checking it out. Glad I'm not the only one.
Core_Dev··on Show HN: I built a text-based business simulator to replace video courses
I'm sorry if I upset your peace of mind.

I promise not to do it again.

Thank you, your comment gives me confidence that I didn't waste a month doing bull*hit.
Core_Dev··on Show HN: I built a text-based business simulator to replace video courses
Thanks, I adjusted the brightness after your comment.

As for the design, it's a matter of taste; mine might be different from yours.

Core_Dev··on Show HN: I built a text-based business simulator to replace video courses
Thank you. This is really cool to read.
Core_Dev··on Show HN: I built a text-based business simulator to replace video courses
Thank you, your comment is truly valuable to me.

I understand exactly what you mean, and the first thing I'll do is improve the user experience so this doesn't happen.

I saw the user journey differently, and it seemed clearer to me.

Thank you. Yes, I noticed this bug after your comment. I have a larger monitor and simply didn't notice it.

I've already fixed it.

As for the way of writing the content, it may not suit you, I intended it this way from the start, and that’s how it should be.

Okay, you can see this however you want.

I'm completely transparent and showing you all the project's work in detail, and I'm not asking for money.

I'm not trying to convince you of anything or prove anything. I heard your comment.

This is the market and this is how it works.

There are a lot of tips, if one doesn't suit you, you can leave it alone or give me yours and I'll add it to the simulation.

In the menu, select "Marketing Simulator" for each element, using the algorithm code I developed in the post.

I'll try to improve the text.

Sorry, English is not my native language like billions of people on the planet.
Core_Dev··on Show HN: I built a text-based business simulator to replace video courses
Ah, got it.

Thanks again, I still need to work on the user interface to make things clearer and more understandable.

Core_Dev··on Show HN: I built a text-based business simulator to replace video courses
I would say that this is literally the idea that I wanted to convey in the project: quite often there are no correct answers.

The goal of the project is to show where mistakes are most often made and try to make them in a simulation, be it a quiz or a market simulation, rather than in real life.

I'm sorry you didn't find it valuable. It happens. I was hoping it would help beginners.

If your experience suggests otherwise, it's not the best option for you.

Thank you again for your time.

Core_Dev··on Show HN: I built a text-based business simulator to replace video courses
Fair point.

Thank you, the task is actually not easy, because in this scenario there is no truly positive outcome; all the options are bad, and you're choosing from the worst, and that's exactly what happens in real life.

I specifically factored this into some of the scenarios. The goal isn't to guess the right one; the goal is to see what the choice leads to.

I'll take your comment more seriously because it may not be as clear as I'd like.

Core_Dev··on Show HN: I built a text-based business simulator to replace video courses
Thank you so much. Bugs are incredibly hard to find, and you helped me out.

Thanks for investing 10 minutes! Hearing that the theory and scenarios provide value is huge for me.

I suspected the UI might be too "loud." It’s a delicate balance between style and usability, and I might have pushed the brutalism too far.

Regarding the Simulation "nope out" moment — was it simply unclear what to do (lack of buttons/direction), or was the screen just too overwhelming with numbers?

Core_Dev··on Show HN: I built a text-based business simulator to replace video courses
Honestly? That is the real reason.

I miss the era when the web was raw, weird, and unpolished. Modern UI feels too sanitized and corporate.

The "Neo-Brutalist" label is just a convenient modern excuse to bring back the fun chaos of the Geocities days without looking outdated. Glad it hit the nostalgia nerve!

It creates a fascinating paradox, doesn't it?

As an engineer/user, I also hate popups, waiting lists, and "urgency." They feel manipulative. But as a business owner looking at the dashboard, I see that removing them drops conversion by 40%.

The simulation is designed to test "Market Reality" vs "Personal Taste."

The goal is to see if you can swallow that pill to optimize the P&L, or if you stick to your principles and risk lower margins.

Both are valid choices in the game.
