I've seen a lot of complaints about the lack of a healer/inn, but to be honest, I find that this is not a big deal. On the first few levels, you are still gaining levels fairly quickly, so it wouldn't take much slime-killing to get a full heal. After those few levels, you should be able to get your clammy little hands on an item that raises your HP as time passes, or for each kill. Both my reward for doing the 'kill 20 wolves' quest and my reward for 'kill 100 slimes' had one of those attributes. At this point, all you have to do is wait a while, or go kill something easier and then come back.
Fantastic game! I really enjoy all of the character interactions and such! My only disappointment was how the plot forced me to follow it right that instant: I finished the game at rank 5 because I did not have time to continue in the arena!
Still, awesome game; definitely going to try again with different factions and personality!
