Very nice!
As you said the grammar isn't great (and Labyrinth is spelled like this). Other than that and the fact that it's rather short, I don't have any real critcism to note. Very slick menu, solid programming (do you have any coding experience with other languages?) and even though this type of game isn't very new, this game adds some original elements (I can't remember having seen any lasershows before).
I'd say this looks very promising. Next time get someone to check your spelling and grammar for you (also a great way to improve your own linguistic skills).
I hope to see more of your work, do widzenia! (that's pretty much all Polish I know, oh and 'trzy pivo' and 'na zdrowie', guess what I did in Poland :p )
