Kanban Software engineer simulation in game.

I encountered such a problem that I have already tried to complete the game on this site more than 20 times and get into the top 50. But unfortunately I can’t get a sum greater than 30,000.

Maybe someone understands this and can suggest a strategy.

in normal mode from day 9 to day 35. I ask you to help me a lot… because I'm already desperate.
