I thought I replied to this... guess it was just in my head XD
Glad you liked the bullet patterns!
Having the character face the enemy sounds like a good idea, I might consider adding it if I ever update this in the future...
As for the graze... unfortunately, it does absolutely nothing. My one mistake with this entry was leaving the game's resource system to the end and rushing it, which is why things like extends never made it in.
Thanks for playing!
