I kinda got that Titan Souls arrow feel and I liked that motion. The only thing I can immediately think of adding would be sound effects to emphasize some of the actions that happen in the game.  I do feel like there could have been a bit more of an explanation of what was going on and what to do.  As you said in the description it is very bare bones and as it is now you probably have the best idea of where you want to take it.
