I played this years back and after coming back to it nearly 8 years later brings me much nostalgia. I enjoy the concept, I like the character design (Despite not being a furry myself)
It's a shame this game series probably won't get much more traction, I think very highly of it as a base defense game with how unique the plot is and the partner mechanic is genius. I hope Zanardi and Liza keep at it with their games. I'm excited for that as well.
