The game is really nice.. but it has only one "bug"... if in the beginning you just increase your archers speed and range, then you can move forward in order to see the enemy, shoot him and then go back again, and the map hides again, so the enemy does not come to kill you... so you just need you archer...!!!!
Tip: Give it a context :D like "you are the best robber and you are sneaking into different buildings to steal really expensive things"... or that "you are an secret - agent - spy"... :P cause it really simple otherwise. (+if you agree)
