This project was interesting. Recently, I've been digging into the functional programming paradigm. This is one of my first tries at it. I've been doing OOP until recently, but this project really was impressive to me. The whole implementation took about nine hours. Functional programming is much less convoluted. I spent more time programming than deciding on a good name for a certain identifier.
Not only is functional programming more efficient, but I can also see that it's much less tedious to write automated tests for. I only have to take care of the local scope of the function I am writing a test for; there is no need to deal with the parent's inherited mess or even any parent's mere state. I just have to write the test for the function.
I have scraped the Cambridge Dictionary to collect the data.

Object oriented programming rose to popularity a few decades ago, along with a great deal of indoctrination and marketing for both the paradigm and related products. It was pushed so hard and so widely that more than a few folks grew into their developer roles assuming it was the best approach to every problem. Of course, it isn't.
(It definitely is useful at times, though, so please don't condemn it just because it's sometimes a square peg in a round hole.)
I'm glad to see you have discovered an alternative, and I hope you will continue to expand your toolbox and aim for simplicity.
Can you give an example of when oop is preferred to functional?
When it's easier to think about a system in terms of objects. The classic example is video game Entities/Game Objects. GUI stuff has also been very pleasant with OOP as buttons and the like are all easily conceptualized and worked with when seen as objects.
ECS is arguably a better for game dev, so even that point is debatable.
