It would seem that the Midas Glove artifact is by far the best, better even than the more costly artifacts. Souls earned are based on total gold earnings. The more expensive cheap unit artifacts just don't equate to enough of an increase in gold.
@mrlordolle Click settings and click to reset your game. The game tells you how many new angel investors you will gain with each reset. Reset pretty frequently at first to gain early production increases that will help you grow much faster.
Thanks for the help. I guess to put it simply, this game doesn't fully explain exactly what benefit angel investors provide. That is why I didn't know if sacrificing for production upgrades would be worth it. Perhaps including an actual production increase value for angels would be more helpful than their effectiveness percentage so it would be more obvious that a x3 overall production increase is worth the 10k angels.
I am currently having difficulties understanding the angel sacrifice upgrades. I can understand that if I am sacrificing less than 2% of my angels for a 2% increase in effectiveness, that I am increasing their usefulness. But how about the x3 production upgrade? I am hesitant to use it because it just seems like a net loss in production, and a waste of angels.
Enjoyable gameplay with tons of helpful tutorials, and I love all the Evil Dead and H. P. Lovecraft references. Looks like I found my new favorite game to play for awhile.
The Flash plugin has crashed and twice I've lost my save data. It's a shame too because otherwise I would enjoy working toward the achievements. For now, I've given up.
