I am aware of that. It's a matter of cost and time on my part. I'm writing and coding the game entirely on my own and have a day job that takes up most of my time. It's a passion project for me, so getting it onto Steam alone is something that I consider a massive achievement 😊 It's why I'll only do a mobile version when it's feasible for me.
You've gotten a lot further in much less time than many others, without abandoning the project or putting it on hold, so I have no doubt that you will succeed in getting this onto Steam :)
But can I ask, do you intend to charge for the (whole) experience once its complete, or will it continue to be PWYW?
