The latest major update introduces structural retention mechanics and a new currency system to Oil Drilling Idle. As the analysis windows contain no performance data, the impact remains neutral. Future assessments will focus on whether the new goal-based rewards and currency limits influence player retention and monetization stability.

Marlvel takeaways

Monitor the 28-day attendance track for drop-off points after the first week to determine if the no-reset penalty effectively sustains long-term habit formation.
Evaluate the Parts currency conversion rate to ensure emergency service costs do not create a progression bottleneck for new players.
Assess the welcome-back screen engagement metrics to confirm if idle earnings summaries successfully trigger session restarts.
