Side quests

The main goal of Block Saga is to destroy the Orbs of Blaukus and beat the final robot boss, destroying the Dark Forces of Evil for good. However, there are many other tasks that can be completed. Here are a few examples of challenges the game will throw at you:

Sword of Nansisius
One player will be provided with the option to pursue the Sword of Nansisius as his or her own personal quest. The Sword of Nansisius is hidden in an underground cave somewhere. The underground cave will be on one of the planets you encounter in your journey. Pulling the Sword from the stone it is trapped in will release the spirit of the Lost Prince/Princess of Nansisius. The player will get to marry the prince/princess at the end, if you are successful with the rest of the game, which you most likely won't be.

The DFE agent
Throughout the game, a DFE agent will be following you around, attempting to kill you and prevent your quest from advancing. You have no choice but to go along with this side quest, unless you want to be dead. You cannot kill the agent until very late in the game, because he is the dark equivalent of a Warlock tier.
