Managing my Game as a Product Thread

I'm a software engineer and i have entered game development field (Unity) for the last couple of months .I have made a couple of games on android using Unity that are only at concept stage now.And i mean by concept stage , that i'm focusing only currently on game play , not graphics and levels and anything else now.The games i have made are similar to (Color Switch) on mobile (The game has no levels , but gets harder with higher score or time).I'm making games with least resources now then decide which game i should focus on after getting feedback from users.I need guidance for the next steps that i should be doing.Like for example should i focus on one game and expand it ? Should i publish and market all of these games with their current state then get feedback with the best game then focus on it ? Should i use ASO (app store optimization) now ....etcWhat i think i need is a game product manager , or an experienced indie game developer that can guide me what should i do for the next step.For anyone who has experienced a state similar to mine , can you share with us some knowledge about how to manage a game in means of marketing and everything else (not code related) ?To confirm my question , I'm not asking for example how to market my games , but i'm asking at which stage i should start marketing my games...etcI know answering this question could be big , but i need just some guide lines for now.
