About Simultree
Simultree is an incremental game in which you monitor simulations of small entities. You play as a scientist, observing the entities as they eat fruit to earn points and keeping them from dying of hunger. You collect their points with a magnifying glass and spend them in a skill tree.
Develop your simulations
The skill tree lets you unlock more entities, stronger entities, a larger magnifying glass, more genetic traits and an automatic point harvester. You can also upgrade more than 50 stats and work with 10 genetic traits. The game includes an Endless Mode and offers 3–4 hours of gameplay.
Take a break
You can draw when you need time away from your work as a scientist. You also sign your simulation report.
