That's normal for just about any coin that's been around for a while. The HUC blockchain is a bit heavy due to all the moves players make being stored in there.

However, that problem is being worked on and a client that doesn't need to download the blockchain will be available.

But... the thing is that some of these minor inconveniences right now are keeping mass flocks of people away, and when they're solved, Huntercoin is going to go berserk. Best to get in now & get some coins before the herds start trampling down the doors.
