When I first started playing Glitch, I assumed that the the musicblocks in any given series would, when all gathered, either play sequentially a longer tune or somehow "stack" to create a multivoiced track.
I was quite disappointed to discover that there was no connection among them that I could detect.
I would love to see a new series of musicblocks that DID in fact fit together to make a greater composition. Could be a quest!
Glitch seemed SO filled with opportunities for small quirky things to add up to bigger, more interesting things. I wish that actually happened more often.
