Hollowpine

Hollowpine asks what a roguelike loses when every run starts clean. Here it does not: the clearing where you died stays burnt, the trader you robbed stops stocking bandages, and the deck you left behind can be found by a later run.

That persistence is the whole engineering story. World state is an append-only event log on device, replayed at launch, with a compaction pass that keeps the save under 400 KB after several hundred runs. It syncs opportunistically so a player who reinstalls still walks into their own history.

Card art is drawn at 2x and atlassed per biome, which keeps the download inside the install-referrer window on mid-tier hardware — the single biggest lever we found on conversion from store listing to first session.
