Last selected Hero and Map is saved
Before this update, restarting the game always defaults to the fire mage and the grasslands stage. Now it saves the last selected hero and map and loads that instead.
Circle challenge improved
The circle now doesn't overlap with the edge of the map and instead moves into the opposite direction in time.
Wolf attack of the earth mage fixed
Wolves that the earth mage can spawn (after purchasing the corresponding upgrade) didn't do any damage, that is fixed now.
Spikes attack of the earth mage
This attack now spawns on enemies instead of randomly somewhere on the map.
Upgrade description fixes
Some upgrade descriptions were wrong or missing, fixed that.
Balancing
Lots of smaller balancing adjustments.
