It's missing otters. This is a travesty!
Jokes aside I played it for like 4 hours straight on my laptop at work. My only complaint is that so far, there's no way to increase the number of drones past 4. I suppose I could do better with organzing the off-island farms and such...
Also, for some reason, the bots on the main island won't touch water. I"ve got two different islands feeding me water, a supply depot set for water, they're all supposed to be loading the central air processor - but they don't touch the water at all.
