Very enjoyable experience. Biggest gripe was the sounds, just not mixed very well, some stuff was a little abrasive (I think the food noise not sure). Almost everything was destroyed because I didn't build any towers. Eventually built back up making sure everything was covered - it doesn't seem like you'd ever need the 4 worker (!) tower upgrade. It actually seems really hard to lose but that's not what I was playing for and I guess you've got the difficulty slider in there. Overall fun, visually beautiful game. Congrats :)
