I have played some and i'm always having to spin around looking where I am at, sadly it usually ends in my death.
I do suggest maybe having a little arrow or dot showing where you are when off screen to help you locate yourself.
I also do have a hard time getting to an exit sometimes because of enemy's bullets always spinning around even after I cleared the level. (Maybe have bullets go around 1 time?)
So far i'm liking what I am seeing. :D
