My first game

Hello everyone, I hope I was not mistaken with the forum thread.
I want to try to create a «hacker» game from my youth. game without effects, 2d. only the player's experience scale, tasks that he accepts with a countdown timer and bonuses at the end. how to finalize saving progress on the server. as an analogue from modern games I see «sandship»
only without effects and graphics as such, more like a website page. tell me if you chose the right engine? experience in sql and python development
Where do you recommend to start? game only for yourself without further monetization
