Hey Jason,
First of all, thanks for trying and for being so helpful with the bug report :)
Unity Cloud error - Analytics is a good guess. We aren't actually using it for anything, at least not intentionally, but had it as one of the installed packages, so I've removed that now. Maybe some Asset we're using is trying to send an anlytics event... weird, in any case. Haven't seen it myself.
"Cannot get component" error - whoops, that's just my bad programming. Some Entity trying to access the Health component of another (probably destroyed) Entity's Health. If you get it again, then getting a log file could help debug that specific case - the log file has some more lines to see more specifically where that specific error stemmed from.
Again: thanks for playing, glad you enjoyed it!
