Cool game. I liked the music and the visuals, it reminds me of an arcade cabinet! I also liked that you added some story elements into the game. One suggestion I would make is to make the world size a little smaller and add a world map to show where you have been. It was hard to tell where to go and where I have been and I found myself just flying through rooms without attacking to try and find the exit. Great work though, I think this is a good foundation for a game!
