idk, i mean, i explored the whole labyrint, trying by brute force and i didn't found a way to get to the end (and believe me, tried re-exploring every part of it 3 times at least), after i reloaded the page the maze was gone, but i have the feeling that i missed something important by not really finishing it propperly
It is quite a big maze, so I don't fault you for taking that exit.
That said: The way back in is not closed off. So if you want to give it another try, you may get it :)
And about the rewards of that journey: They do not consist of anything pertaining to the gameplay of Pixelgrab. If that is any consolation :)
