I'm assuming that I'm putting money in the cash register of this repair shop every day as part of the strict ethical code I've sworn to uphold. I alone carry the fire..
For some reason, I can't get the 4th reaction on several items - Live cat, for example. I meet the requirements (100%, 100%, 0%), but nothing new happens.
I bet the poor schmuck that lives on the ground beneath this castle never has to fertilize his crops, with all the dragon carcasses that rain down every day.
This game could have been fantastic with a tech tree instead of linear upgrades (faster speed, more magnetism for coins, different weapon types, etc.)
Though as it currently stands, I think this game taught me more about the inherent flaws of capitalism than anything I ever learned in school. Think about it - The bigger (and more powerful) you become, the harder you have to work to sustain yourself. You become more inefficient as your size increases.
This might be obvious, but if you're struggling to have enough cash it's very profitable to sell monsters. Cerberus takes 1 magic stone, 1 blue (or white egg, it seems to alternate for me) egg, and in 6 days can be sold for $170. I kept one monster on display, and kept farming cerberus and selling them in the lab - rolling in max upgrades in only a few months.
