What Did I Do To Deserve This, My Lord?!'s premise is incredibly simple, but at the same time incredibly complex. Playing as the God of Destruction, your ultimate goal is to keep your prized servant, Badman, safe from any pesky heroes that decide to slay him. In order to keep him safe, you'll need to create a labyrinth and populate it with all sorts of creatures.
Gameplay is split up between phases. You begin with a limited pool of energy that you use to destroy blocks. Destroying green blocks spawns green blobs that serve as the backbone for the ecosystem you'll need to construct to breed larger monsters. Badman's complexity is built around developing an ecosystem that is able to remain balanced but also foster growth. The system is further complicated by the fact that you have very little control over how things will play out. You are limited to the ability to break rocks with a pickaxe; giving you full control over layout but very little else. It's not easy and will usually result in a number of frustrating restarts before you get it right, but when you do, it is rewarding.
Eventually, heroes will come knocking. The inclusion of heroes presents a further change in the ecosystem dynamic. Provided you have enough energy, you can continue building your maze and ecosystem. You want a balanced system, but you'll need stronger monsters to fend off stronger heroes (and eventually parties of heroes), so you might need to throw the system towards generating an army of lizardmen.
Heroes normally come of their own accord, but there are times when you may want to invite them into your lair. Between stages, you are scored on time and expended energy. You can also use unused energy to level up your monsters -- so efficiency is key to your operation's success.
