A Few things I noticed...not sure if they matter..
In your 'Signalling' Group...Your's differs from the Tutorial...As seen here
Your events differ considerably from the Tutorial Events ..it may cause problems
Specifically when Setting 'Block.peerid ' yours is set up differently from the tutorial...You may want to check any errors The tutorial says to associate it with MyID not PeerID...
You have both the host and the Peer set to the 'same ID' from what I can tell it should be two different ID's
Also..that tutorial is for Mouse Controller..I am not sure if it works the same for Touch....I guess it should but there might be differences in the setup
That's all I can see at the moment..
