Hey naranjaroc, if you're talking about the stone teleporter: you do need some free space, and there must be a worker working on the teleporter. Also, rocks will only be teleported if there are less than two left. Hope this helps!
i have an idea, if campaign is extended you could add that if you complete all the campaign you will be able to choose one hero for free. this is only an idea but i think is a great way to make people continue the campaign, because sometimes is a bit tedious
campaign difficulty is ok, i don´t know why are you complaining about it is too easy. the fact is that it has a lot of battles to complete only 1 stage
The game doesn't work on chrome. If you use a different browser, it probably has something to do with your unity web player. Try to deinstall it and install the new version from: https://unity3d.com/webplayer
