I was expecting another crappy farming idle game... Boy, was I surprised! I got something weird and surreal and I'm still not sure what happened, exactly or what that tentacle-rock thing was.
Zero complaints, though; progression was not overly slow in the "musical" round and the "skill/speed" round had a good difficulty curve and it was intuitive to figure out which colour does what. It took a swear word or two, but I /did/ eventually finish the fourth quadrant of the second round.
Bravo; I can't give this anything but 5 stars.
