I like a good RPG subversion, and I think this one delivers. It made me smile, at least.
I like your characters, and I think that style works well. The designs are nice. It doesn't always match with the tiles and the backgrounds, though, and there's different pixel sizes. That's an area where you could improve, I think. There were also a few grammatical errors - nothing major, just a few things here and there.
I'd be interested in seeing the rest of it. You have a fun start for a game here, I think.
