How To Better My Game's Statistics?

Introduction:
Hello, I am the developer of a ROBLOX Political Simulator Game, about a week or so the game saw a spike in D1 Retention and Unique User Play through, which lead to a spike in players for a few days, since then a lot of my statistics have fallen below average (however player count has increased post-spike) and I cannot find a specific reason/s why.

Why I’m Posting:
I come here asking for constructive feedback on current game features and possible new features you think could help improve certain statistics. Some of the more desired stats I want feedback on is how to increase D1 and Session Time. Thank you.
