It's a fairly fun title so far. Could do with a better soundtrack though, but there's time for that. Pay heed to the Rune Upgrades, the fork in end of the top UI. Read it all (games is paused while you in that menu), and you'll have a way easier start with certain choices that get you to save some money and time. Two choices in particular are vital as soon as you start the game before doing anything. Those points will increase frequently during the first 3 waves, and it's good to get at them as soon as they do to muster the benefits ASAP. Don't forget that right click puts higher priority on the blocks (blue indicator) and to pay attention to the ones with high gold, scrap them earlier. I'll follow this title.
