About this game
Keep Feeding the Altar
Kill roaming critters, let your cultists process their bodies into meat, and offer sacrifices at the Altar to keep your cult alive.
Your Guardian Power
Strike enemies with mouse-driven attacks while your cultists focus on their ritual work. Every sacrifice empowers the altar and grants you greater divine strength.
Survive
Critters grow more dangerous over time while the altar demands larger and larger offerings. The moment sacrifices stop, the countdown start and Altar collapse begins.
Unlock Upgrades and Power
Earn Tithe at the end of each run based on total meat sacrificed. Spend it to unlock upgrades, improve efficiency, strengthen future starts, and discover new ways to survive longer.
