I also liked this, although it could really use some polish. It actually reminds me of something very similar I made.
The automatic battling is done pretty well, considering most RPGs of this type are just button mashing anyway. There were some cases of "artificial stupidity" where the AI wasn't so great, but nothing too bad. I think you should've done a simple menu system instead of having to talk to people to find out basic information; this could also give room for more NPCs. Also agreed on the inventory thing.
I enjoyed the simple charm, especially how you can breeze through and just bash away at enemies. It's really just simple mindless fun, and I played through in one sitting. The old RPG Maker music was kind of a letdown at first, but it's actually sorta fitting when remixed the way you did.
I did notice one big bug you might want to look at. If you die during a boss battle and return to fight the boss, he's counted as dead anyway. You should probably turn the variable to true after you defeat the boss. :O
But all things considered, I liked it.
