Pocket Dungeon Survivor

Pocket Dungeon Survivor is a roguelike survivor game confined to a single screen, and the confinement is what makes it work. There is nowhere to retreat to and no map to explore, so surviving means using the space you have rather than finding better space. You beat the enemies that come at you and last as long as you can, upgrading your character along the way with new attributes and abilities that reshape how a run plays. Skins are in there too for players who want their survivor to look different. It is a compact take on a genre that often sprawls, and it suits browser play precisely because a run is short, self-contained and immediately repeatable.
