Winnies Hole is an indie roguelite strategy game where you take on the role of a symbiotic virus spreading through its host. You must explore procedurally generated internal worlds, strategically placing Tetris-shaped virus blocks to capture cells, collect resources, and unlock new abilities. The game features a unique turn based combat system, in which available actions are randomly generated on a special Brain board each turn. This forces the player to carefully select block combinations to activate powerful combos and adapt to the limitations of the host's body.
