I've been playing for a few hours now. In that time, it's told me that there's a new version of the game and locked up twice.
If you're actually releasing new versions multiple times a day, that's ... excessive. If not, there's a pretty serious bug.
Quick bug report: on rescue missions, the person you're rescuing will cheerfully hop into the ductwork with you, but at least on the one I tried, there seemed to be no way to lure them back out again, and you can't push someone in the down direction, and (probably a good thing) if you push people into the space over a vent, they don't fall out.
The spy I rescued set up housekeeping in the ceiling and is currently living her best life, so I guess it's not all bad, but in general probably not optimal.
