But initially it was just a modification before VALVE decided to help and took students from DigiPen into their team thanks to their development of Narbacular Drop, which was the beginning of the creation of the portal. It's longer than Narbacular Drop. It's an interesting puzzle with great humor. Not a bad plot and good physics. And it is very addictive with its pleasant gameplay. Who would have thought that it could still be made better. Before the release of Portal 2, but this is another no less interesting story. Well, in this part, the Russian localization sounds very monotonous. Despite the fact that the original was voiced by one girl, she tried to make the characters unique and it turned out well. Our localization sounds the same and could not achieve the same. But even this became better in second part.
