Run life simulations
You're a scientist who run simulations of small entities in order to understand them better!
These entities will yield points upon eating fruits, but you need to make sure they don't die of hunger. :(
Use your magnifying glass to retrieve these points and spend them in the skill tree.
Unlock new things to play with
More entities? Stronger entities? Bigger magnifying glass? More genetic traits? Automatic point harvester?
Do what you want, you're the only scientist anyway.
Draw
Why? As a scientist you need to take some time off.
Don't procrastinate too much and don't forget to sign your simulation report!
