To easy the game play just replicate the sounds until you head on towards the next check point, and even counting the amount of times you've traveled around the circle in certain situations aids you A LOT.
To get through the difficult parts of the game you need to start using the sounds as a advantage, and then your goal is to replicate the sounds again and again until you get to a check point. You would also need to do some counting just to get through the even harder areas.
2/5 The graphics are amazing but there is really nothing to strive for but to conquer the whole battle field. The AI is great but when against them with exact amount of ships they always seem to be destroying my ships because they might have a bigger damage output. The game overall has potential but it is not fun and not unique in any way and is frustrating to compete with the AI that has a higher damage output and has no disadvantages with the percentage value of sending in his units.
There's only one hero to choose from and the game itself has turned into a disaster because it lacks creativity and its just a standard game where you can just simple kill every solider in under a minute. If you were me you should take some of the ideas in Kingdom rush and implement in your own games.
