I am planning to start game devement on my own

As the title says, I am planning to depart on my journey to do game development.

As of now, I have created a game onto itch.io which you can see here.

I have uploaded a simple game to familarize myself with the Unity engine and I hope that I can transition to develop games full time.

I do foresee some challenges ahead of me.
I only know how to code. So I will have to make do without music, art, 3D modelling and so on.
Even then my main language is not C#, the language that Unity uses.
I am familiar with C/C++ so that won't be a major issue.

I have a day job so I am only working on my game on my free time.
I plan to save up to use the assets from the asset store to make a decent game.
Not too ambitious, just decent enough. Probably a 15 minute gameplay.

Even so, I still have a long way to go to transition to making games full time.
