What Is Melt and Fill?

Melt and Fill is a hypercasual strategy game by VOODOO that leverages satisfying melting mechanics to drive engagement. While the core gameplay is highly effective at attracting casual users, the product is currently failing to retain them due to severe technical instability. The app is currently in a critical state where technical debt, specifically regarding progress persistence and monetization bugs, is actively driving negative sentiment. Immediate intervention is required to stabilize the experience before the product's reputation is permanently damaged.
