That was the fastest Game Over I ever had in any game and that is somethink that will go down in my history. Thank you! :D
After a while I was able to get past the first stone - no idea how it works but I did it! Another achievement! :D
Once you get past the first stone it's fun.
Tip for the others: hold arrow keys and pause unpause/restart the game until you finally get past it. No idea if that is intentional and if it works the same for the dev.
