Good suggestions ;D It is important that you always close the menue before running further that means you have to push the Left Arrow Key until it closes. Yeah my English got way better today, but I havent reworked these parts until, now because I am currently working on a new project but you are right I will deal with that in the next time. To the unit sounds, I also thought about that, but for me I didnt like that then and removed it again and I dont think that I will do that again. The Monsters in the first part, yeah good it is only the first part, if you know that part you are through in 12 minutes and using escape is something which can be seen as normal there and also in other parts of the game.
What I take really seriously is the grammar issue. You have to keep in mind as a map maker you get better and better from map to map, your triggers get better, your ideas get better, your terraining etc. and on the first two maps that has been really early in the game of course I reworked many parts but on a limited scale. The first map is from my pov nothing more than a test map (besides the story part, that's gonna be important), there I tested the most important features and then improved them a lot in the following maps.
So I recommend as the review of the Moderator says, continue playing and check out the next maps because they will get better and better and always follow the streets, they are always going to lead you to your destinations.
