Single player good, coop very broken

The good:

Single player is a fun game, with a great combination of genres. There are some minor interface rough spots that come from it being an iOS port, such as buttons lacking shortcuts, or scrolling being non-obvious. I did encounter bugs with controlling the cursor during a build phase that went away after a level which was a little frustrating. However, the game play itself is fun and the design inspiring.

The bad:

I bought this for the coop angle, but its too broken to use. Getting a match with more than one friend to work is impossible: friends just fail to join the session, or the match never starts if they do. Matches with two people are fun until one person suddenly is "out of sync" or is just disconnected. Its a huge exercise in frustration, since when it works, its great. Foursaken Media, while clearly made of nice folks, dont make any effort to have a support process beyond a catch-all "contact" address, which they dont respond to. Theres no support forum or ticket system or anything. Ive been reporting the problems for weeks, and had to resort to Twitter to get any kind of acknowledgment.

Conclusion: Perfectly fine for single player, but avoid for multiplayer. Dont expect support.
