You're one cell, in a new world.
The free demo for Salty: Evolution Simulator is live — download it right now from the store page and start your climb up the food chain. And yes, we're part of the PvE Survival Crafting Fest through Sep 7, so if you're browsing the fest, welcome.
What's in the demo
Explore a hand-crafted saltwater ocean — glowing vents, kelp gardens, and a bioluminescent jelly cave.
Hunt smaller cells: engulf them whole, or grow grappling tentacles and reel them in.
Craft the start of 21 organelles and abilities on the crafting wheel — nucleus, cilia, flagellum, tentacles, and more.
Survive — keep your cell fed on fiber and lipids, and watch out… the viruses are coming.
Discover 17 microbe species and log them in your Compendium.
Help evolve Salty before launch.
Salty hits full release on November 10. This demo is where you shape it — use the Report a Bug button in the pause menu, or post in the discussions. I read everything. If the primordial soup grabs you, a Wishlist is the biggest way to help a solo dev. 🦠
