For some reason I'm not getting any achievements. I not only beat the zombie dragon, but also completed the arena which should've netted me two of the badges... but I got nothing instead. Any help?
If you leave as soon as you enter, the wizard "changes" you, but you retain your same character. You can even swing your sword, go through small gaps and holes, an complete the level.
It would be nice to have a little click counter in the corner, getting all the way to the end of a level and discovering you're 1 click over is really annoying. Especially on 45.
What the &^%$!!! First "wave" and the running zombies come up and kill all my partners when the barricade is at full health! If they ever make a Last Stand 3, they REALLY need to fix that.
A hint for the heroic/iron challenges. Then Hammer + Nail icon when you select the challenge is the tier upgrades you can use from the upgrade menu. Resetting and redistributing depending on what tower you're using the most is key.
