I tried a few of my own songs and all I can say is the game is downright impossible but when I tried the normal way it was pretty easy solid graphics and a good shmup.
This was my demo for a game it is far from complete I posted it for feedback and it was stolen from me all I can say is this is some bullshit Im glad I looked this up.
