I don't have enough free time for this game. No, this is my first and only game.
I have my own plot plan, thank you

Yep, do stick to your own plot. You have gotten this far, but if you want to ask for suggestions go for it. You are not bound to accept suggestions.
And please don't rush this game!
Just be mindful of what you already have presented and keep the timing of events in a natural progression. I don't know how aware you are, but the plots and store line you are using has a natural flow to it

I'll be willing to throw my hat in the ring for your next project, but that ought not be for a long while before you are ready to start another project.
