Girl Rescue: Dragon Out!

This is a portrait-oriented, hypercasual puzzle game that can be played solo in short, interruptible sessions. While the core gameplay is relaxing and offers high replay value, it is heavily monetized with frequent, long ads and a pay-to-win structure that makes progression difficult without spending money or enduring excessive ads. It's best suited for players who don't mind a challenging, ad-heavy experience and can tolerate a pay-to-win model.
