Really good. I wish there were just a few more levels on Kongregate (I understand there's a mobile version so most of the levels are there. I just think a few more might be nice.)
For me, it glitched on the "Time of Day and Elements" page. I made it daytime, then accidentally ran into the vampire before he was completely dead. Now the hero isn't there anymore, and it's stuck on that page. Good concept though.
We haven't been able to replicate it, but we'll keep looking into it
