Here are the comments that I promised earlier. I hope it's not too late. Most are corrections to the English, but there's some other suggestions, as well.
Try rewording the prologue to:
"In the year 20XX, humans left the Earth and started to live in outer space.
After 100 years of living in space, humans can eventually visit the Earth again, but, unfortunately, they can't live there yet because the air is still infected by a radioactive substance.
You are an astronaut who has been sent to Earth to recover an artifact from the past.
Your spaceship landed to the northwest of the mission location. Recover the artifact and leave the Earth as soon as possible.
Be careful."
General comments:
Getting and dropping of objects is very buggy. See Adventuron's comments on this. It desperately needs to be fixed.
As all your responses are fairly short, you don't need to follow them with :press_any_key; I found this quite annoying.
Instead of allowing N, S, E, W from every location, block off some of the exits so that it is more like a maze and you have to do some serious exploring to find the important locations. You can still keep the routes between the spaceship, house and mine fairly short so that you don't annoy the player.
In Front of Spaceship:
Full stop after "spaceship" should be grey, not red.
Spaceship:
There is no image for this location.
"You enter in the Spaceship.." should be "You are in your spaceship." and delete the red full stop after "spaceship".
There is an exit called "Exit" when you get to the end game, but it doesn't do anything.
"A Pc Computer" should be "A PC" or "A Personal Computer" or "A Computer", as "A Pc Computer" means "A Personal Computer Computer". I think "A Computer" is better.
X PC: "with a huge data" should be "to a huge database"; "Unfortunally the" should be "Unfortunately, the". The second sentence doesn't make sense at all. Try "It can be used to research unknown things by uploading information."
X CAMERA: "Its" should be "It's"; "should be used to upload the travels in the computer and send to data base" should be "can also be used to upload photos to the computer".
GET CAMERA: "on the bag" should be "in the bag." Huh? What bag. You aren't carrying a bag. Its better just to say "You get the camera."
When you DROP CAMERA, it says you don't have it, even though it's in your inventory. Do you have a typo in your :match statement? See Adventuron's comments on this.
UPLOAD PHOTOS: "for your computer" should be "to your computer"; "Now you have acknowledge of the items" should be "Now you know what those objects are".
You can UPLOAD PHOTOS more than once. Set a boolean the first time you do it. If the boolean is set, say "You've already done that."
USE SPACESHIP didn't work for me, as I had somehow dropped the required object and couldn't pick it up again. You should preferably not use USE as a verb.
You need some way of knowing how to take off once you've recovered the important item. The traditional way of doing this is to provide a big red button labelled "Take Off" or "Blast Off" or "Lift Off". When you PRESS BUTTON without the required object, it says something like "Not until you've completed your mission." When you PRESS BUTTON with the required object, it gives you the congratulations message.
Huge Hole:
"I" should be "you" (twice) and add full stop at end of sentence.
Beautiful Lake:
Delete red full stop.
X LAKE: "is just" should be "it's just"; "but looks have" should be "but it looks to have"; "Is a fish?" should be "Is it a fish?"
It doesn't appear that you can do anything with the fish.
Old House:
"Theres a" should be "There's an"; "Looks no one live here" should be "It looks like no one lives here".
"A Couple of Unknown Objects" should be "Some Unknown Objects", as "a couple" means two, but we later find out that there are four.
X HOUSE: "Very dirty and the walls looks like it can go down in your head at any time" should be "It's very dirty and the walls look like they will fall down at any time".
Provide a response for ENTER HOUSE.
TAKE PHOTOS (second time): "You already take a picture" should be "You've already taken photos of the objects".
When you return to the house after uploading the photos, "Now you know what are this things" should be "Now you know what the objects are". However, this isn't really necessary, just omit the press_any_key and list the objects as normal.
"An Pickaxe" should be "A Pickaxe".
You should be able to EXAMINE things without them being in your inventory. Use is_present rather than is_carried.
X TRAP: "caught bears" should be "catch bears".
When you drop the pickaxe, you get two responses. The second one has two full stops.
When you drop the trap, you get two responses. The first one says "trap" and the second one says "bear trap" with two full stops.
When you drop the gun, you get two responses. The second one has two full stops.
When you drop the bomb, you get two responses. The first one says "bomb" and the second one says "kind of bomb" with two full stops.
Cave entrance:
X CAVE: "My mission is take the object that was hide in that cave." should be "Your mission is to take the object that is hidden in that cave.".
X ROCK: "Its" should be "It's"; delete "I can't just take off."; "I destroy" should be "you destroy".
DESTROY ROCK says "How should I do that?" This should work if you've got the pickaxe. Also allow for synonyms like HIT, BREAK, CRUSH, SMASH. This is better than USE PICKAXE.
When you leave the cave, "follow" should be "followed"; "you using the pickaxe for destroy" should be "your pickaxe when you destroyed"; "and cornered" should be "and it cornered".
"H* Be prepare at the next time" should be "Hint: Be prepared next time".
Add an extra space between "GAME" and "OVER".
"click" should be "Click".
When you DROP TRAP, you get two messages. Delete the second one. You're probably missing a :done; after printing the first message or you're using :drop; when it should be :drop quiet="true";.
When you exit the cave after setting the trap, "caught on" should be "caught in"; "violentely" should be "violently"; "loose" should be "free"; "some agonizing" should be "an agonising" (unless you're American); "lose his force... Now him is about to die." should be "loses his energy and is about to die."; "for help him, this" should be "to help him. This"; "certainly" should be "is certainly"; "if is loose" should be "if it is loose".
Inside Cave:
There's no room description.
"Here is, my mission is take that capsule." should be "Here it is. Your mission is to take that capsule.". However, you don't really need to say this, as you said it before entering the cave.
"to try open" should be "to try to open". You don't need to say this, but you should say it if the player tries to OPEN CAPSULE.
"I should" should be "You should"; "Spaceship" should be "spaceship" and there should be a full stop at the end of that sentence.
You automatically take the capsule. It would be better if you had to manually take it.
"A Time Capsule Full Of Memories From The Past" should be "A Time Capsule". Provide the other info when you examine it.
You can't EXAMINE CAPSULE or DROP CAPSULE.
When you enter after setting the trap, "After take" should be "After you take".
End game:
After getting your hint to USE SHIP (I would never have guessed that): "You complete you mission. Recover" should be "You have completed your mission. You have recovered".
"its past ancestors" should be "your ancestors".
The last sentence says "100 years ago", but the intro says "1000 years". I think 100 is a more reasonable number, so change the introduction to 100.
"After open it" should be "After opening it".
"You had some weird feel that book has something with what happens with the earth." should be "You had some weird feeling that the book has something to do with what happened to the Earth."
"the humanity" should be "humanity".
"After read the book you notice how absurd was that theory and start thinks that you are crazy." should be "After reading the book, you notice how absurd that theory is and start thinking that you are crazy."
"thanks letter" should be "thankyou letter"
Adding the credits at the end is a nice touch.
"comunity" should be "community".
"alot" should be "a lot".
"answear all" should be "answers to all".
The end says "1 / 3 secrets found". Did I miss something or is that to be added later?
