Will streamers play it? Will people buy it? I have no idea and no way to know really…

You can influence some of this directly, but yeah, there will be a lot of unknowns.

In the end of the day I just want to say I did my best and worked as hard as I could.

Valid and healthy goal! I do want to add: you can’t do everything yourself. Don’t be afraid to lean on your network to get help where possible. You can fill in some of those unknowns with resources from the indie scene, but that will also take time, effort and sometimes money.
