I love the idea with the boss hiding in the buildings. Besides that the game has several problems. First of all, the game slows significantly down when new units appear. Even in lvl 3 with about 20 units on the map the game lags. Furthermore, it is resource intensive. In lvl 3 it too 77 % of my CPU time. That is too much for such a simulation. Also there is no button to change the difficulty. It says "Completed on easy" but how to activated hard mode? I really like your game and would like to play it to the but I dont know if that is possible, considering the preformance probs mentioned above.
I like this retro style! But also I'm gettig tired to tell you guys that most people outside the US don't have their "z" between "v" and "x" !!!!!!!!!!!!!!!!!
