Do you know there are expansions in this game? (This is an ECG, after all.)

It doesn't matter much, given that everything is free anyways, but expansions up to this point:

v1.0.0: Core set

v1.0.4: I like to charge it

v1.0.7: Freezing the world

v1.2.0: The awakening

v1.2.3: Throwing darts

v1.2.6: Artifacts of history

v1.2.7: Revised core set

v1.4.1: Your math party

v1.5.0: The art of runecraft

v1.5.1: Not called lifesteal

v1.5.6: New sources of power

That's the core set plus 10 more expansions, free! I wonder how much most game makers would sell all this content for.
