New version available. I have already drawn textures necessary walls for the first 10 levels, and now the first episode is complete (although you can choose any level, but with a little trick), plus I have added selection of difficulty, because depending on the difficulty, level will have more or less enemies.
Now you can kill the guards, even though they do not walk, it seems that someone shot him with a sort of stun ray that caused ....

no, the truth is that it still needs a bit of code so they can walk.
Although it seems that has not advanced much, but believe me it was a good amount of code I've added.
The next version will have the guards walking, (patrol and chase modes).
