Hi, I have some problems with the upgrades.
I have played this game before Kongregate included the badges and already max out most of upgrades. But now that I play it after the bades are included my upgrades are still max, however, it doesn't work. For example, my health upgrade is max, but when I play I only got a small portion of my full hp. Also, I got launch to Max, which used to take me to at least stage 3, but now it take my only to the beginning of stage 1. And I can't upgrade them, because they have already been maxed out.
This is a bug in game, or I did something wrong. Btw, new version of this game is great, I would change from 4/5 to 5/5.
Tips on undead beast king: wall is the key, the regeneration of mana is faster than the destruction rate of the king. Sometime, place the wall in the king's position may avoid damage done to wall. Only little goblins can attack it. The rest is up to you, I recommend dragon and long range squad. :D
Thanks, added to my to-do list.
