Slash.io: Sole Survivor

This is a fast-paced, likely portrait-oriented action roguelike that can be played in short, interruptible sessions. While free-to-play, progression heavily relies on watching ads or potentially paying to overcome challenges, making it lean towards a pay-to-win model. It's best suited for players who enjoy quick bursts of intense gameplay and don't mind a significant ad presence or a progression system that can be accelerated with spending.
