When engaging the Dragon, make sure to create enough empty tiles around it (two in each direction), so your heroes will heal by randomly walking around, and hit the dragon when passing by.
Nice game. As TBTabby said, the cooldown time makes most of the abilities useless, which makes some characters with fast attacks extremely effective, and others with powerful but slow attacks extremely senseless. I think it the game would be much more fun with a higher number of effective characters. I enjoyed it nonetheless. Some more levels would be cool. Or maybe a preview which level will show up next.
Nice logic game. I really liked the levels - not too hard, but always challenging. I think lv 28 was the hardest of all, the following two were relatively easy. Really took me some minutes. Besides, I thought about the drag/drop of the balls - wouldn't it be easier just to click on one of the factory icons?
I pressed the mute button and instead of silence, I heard another music play. What went wrong here? Then, the game froze my firefox completely when I picked up the plane. It seems to work only with the mute button. One other thing - I think it would be better if the game was controllable either by mouse or by keyboard completey, if possible - rather than mouse and keyboard mixed.
Apart from this and from the story that I found quite ridiculous and disappointing, the game is really really nice.
Thanks for this nice game! I didn't expect much of it when I realized that a shooter is hidden behind that beautiful intro. Then, it turned out to be a very well balanced and challenging game. It was neither impossible nor time-consuming even in the endgame, as many games of this type tend to be. Really liked the trophy badge :)
