My Game Has Very Low Stats

Hello. I have made a minigame game. I ran ads for it for around 6 days [16 credits per day].

But the players seem to just leave fast and aren't ready to wait less than a minute for a round to end.

It's a round based game so sometimes players should wait a bit before being able to join a game.

The stats are horrible

3 Minutes play time, 1% D1 Retention, 0.24% PCR, and 1.83 ARPPU.

The game looks promising and a lot of people liked it. But ad players aren't liking it at all. I tried limiting the ad to certain genres, regions, but no improvement.

The CCU was averaging 1-7 which I realised is very low considering the 16 ad credits.

I'm fixing bugs, adding more QoL features, and better long term systems. And I'll try advertising again 16 credits per day for a week soon.

But is there a specific reason why the game's stats is horrible ?
