Merge Plants – Monster Defense

This is a portrait-oriented tower defense game with a standard progression system that can be played in short, interruptible sessions. While the core gameplay is mindless and can be played with one hand, progression is heavily gated by ads and pay-to-win mechanics, making it difficult to advance without spending money or enduring frequent, lengthy advertisements. It's best suited for players who don't mind aggressive monetization and are looking for a casual, low-demand experience.
