Thank you, HakuPL for your advice.
Let me start by saying that I tried your game on Windows XP and it was running smoothly.
---------------------------
It could be the service pack or something that you installed on XP that is not installed on XP by default.
The basic premise of the game is something that we have seen many times (in many other games, on many different sites) HOWEVER if i can give you some usefull tips:
- I loved the beginning (the message boxes). I know you made it that way because you are not a graphic designer but it fits your game. It's very simple (you could say primitive) but it made my imagination work. Before game started I thought more of the game as something action adventure + puzzle gameplay. I would consider leaving it this way and changing gameplay into something more interactive. I mean, think about that: game starts with that message boxes, than you are left with an www adress. When you go see that site you end with simple page about, let's say, doing honey. And somewhere on that site you put your puzzle. When gamer will solve it he will gain next address (or some key word to google) and game goes on.Try making it as more mysterious
I mean, think about more interactive way of your game. I'm not saying "make better graphics and all" but by putting some effort (creating fake www pages and stuff) you make it more interesting. Think about writing some simple story. Player will want to know the ending, will go from one riddle to another and by reaching end he will feel an accomplishment. Besides, it's a clever way of making your game better without messing with your first idea 
I have not seen a game like this(other than a game where the player programs an ant to get through a door using a real programming language... i forgot what it is called), but the story is similar to Portal 2.
I completely forgot that I had Anzen the robot say that the control panel is connected to the internet. I do not plan on making this game online, but I suppose I could make a fake browser with built-in fake web pages. Thanks for the idea.
- If you don't want it to be the way I wrote in the above indention; try to spread your text evenly. One message box has one sentence and another has 10 (which is somehow annoying and boring to read).
I put a load of text in one of those text boxes because one of the people testing the game said that the robot's monologue was too long, but I agree that text should be spread out evenly with text boxes.
- Some maps are to big - it's no fun to move all the way to the right corner just to go 2 blocks down and move all the way back. Either way make them smaller or consider making more maps.
I made a bunch of maps. I was originally planning on having the release of the game have 50 maps or more. The large map(100x100x2) was meant to be a joke to prove how large the maps can be, but that's not the maximum size. The maximum size is 100x100x100. I couldn't make an interesting enough map that is that large, so I just settled with that size.
- I know that this is just a debug version but try making some achievements or goal for gamer to play your game. Make 3 more maps but "blocked" so until the player passes previous one he will have no access to them. Maybe think about making some medal/trophies for gamer so he will have purpose to play the game.
That is a very good idea. I can not implement it properly yet because I haven't implemented a save system, but I will try to make "medals" for very strange accomplishments, like getting through that big maze.
- why not making some list of best (you know - best time, best player or sth like that). Players like to compete with each other.
I have many ideas and I'd like to share it with you so tell me if you want more (or, if you want me to be more specific about some areas of game [graphics, gameplay, story]) and I will be more than happy to help you. Anyway, keep up with the good start and work and sorry for a bit messy post but right now it's 3:00AM here, in my country, so I'm a bit tired 
A high score list? I suppose I could keep track of how many moves the robot makes in order to get to the exit. Once again, that would require a saving system, but it should be relatively easy.
So just to reiterate to make sure I get what you are suggesting:
1. Make a false web browser with a series of false web pages to add mystery to the game's story.
2. Make the monologue flow better.
3. Make a save system to keep track of the finished and unlocked levels as well as a high score list.
4. For the demos, get rid of the 100x100x2 map and add more maps.
I'll get started on that soon. School is starting again soon. Between normal schoolwork in the morning and making video games with a team at a school that I go to in the afternoon, it should take quite a while to implement these changes for new demos.
Thanks again for the great advice, hakuPL.
