What is One Turn Kill?

One Turn Kill is a single-player PvE card game developed by DenDen and published by Waku Waku Games. Its battles ask you to defeat the enemy within your first turn.

The deck is limited to 20 cards, and drawing cards forms the cost of playing them. Cards and skills can support one another, so deck construction and action order matter.
