The Last Survivor.io

This is an intense, solo survival roguelike played in short, portrait sessions that can be easily interrupted. While it offers high replay value and is playable offline and one-handed, progression is heavily gated by energy timers and a pay-to-win monetization model that can make it difficult to advance without spending money. It's best suited for players who enjoy challenging, fast-paced action and don't mind a steep pay-to-progress curve.
