I played through act 1 and a bit into 2. Music is great, but I knew that before playing it.
Its nailing the most important parts for an RPGM game; nice atmosphere and interesting enemies. It made me want to find out what the story is about.
It really seems like you know what you're doing here so I don't have that much more to say, wish you could walk diagonally and there are some sprite sorting issues. I'll return to play more later.
