Hello,

idk why you bought this game but if you did here are some basics:

-there is no story (so i really don't know what's going on)
-your only task is to get the blue card and find the white door with a blue "line" (red line means the door is closed, green means open and blue exit)
-i don't know what the green textbooks are for
-you can only pick up bullets (red box) if you are holding your pistol in your hand
-your knife is as strong as your pistol (it does the same damage)
-your only task is to get to the end of the level (as far as i know)
-yes, the game is 11 levels long

And yes, thats it;
there is nothing more to this game

Thank you for looking at my "guide"
