Vessel Thirteen

About this game

You were grown in a lab to hold a blood devil, and it keeps score. A story-heavy escape with karma and sin: every mercy raises karma, every kill raises sin, and sin thickens your blood. Three weapons (fist, blood arrow, demon sword), kill / run / mercy at every fight, a blood meter that refills faster when it runs low, sage mode that bends time but corrupts your soul, and endings shaped by who you spared and who walks out with you.

How to play

Fights: tap a lane or press arrows / 1-3 to attack; weapon button or Q swaps fist / blood arrow / demon sword; SAGE button or S slows time (5 uses per level, costs soul). M mutes.
