Bravo! I think I am in love.
It may be the music alone that made me fall, but I was also overwhelmed with the simplicity of the game and amount of dexterity it takes in some the later stages.
I really was overcome with a frisson of thrill and sensation of wonder as I pursued my way through the "end." The game definitely has a high replay value and enjoyability in my book.
An absolute 5, albeit it's lacking a certain freshness. I love it.
Games like these are best played in a "gaming environment."
TLDR; Great game! 5/5
