My first attempt at Blast Network, my client completely froze in the middle of a match. I had to force quit it and launch another instance, wherein it returned me to the match and I was able to continue. Of course, during that interim time I had died repeatedly.

My second attempt, I seemed to be completely desynched from everyone else. I couldn't move more than a couple of steps in any direction without snapping back to my start square, I couldn't pick up any items, and my bombs wouldn't show up. I was still able to be killed, though, both by other player bombs and the rockets coming from the sides.

Third time, just for the heck of it--froze the client mid-match again. Huzzah!

So, yeah...seems like this is pretty unusable to me right now.
