Hey uh, Yeah. DO NOT go past the tutorial in the beginning. Onbly do what it tells you. :P I started the first match by clicking all my cards, anmd after I won the match, the tutorial screen never went away. :L
Darn it! D: I found a spot on the last boss where I could sit there and not be harmed. I stayed there until he got to 50% HP. Then he fired rockets which drowned me out of there. :/ Then I died. (Oh yeah, and the secret spot is on the right of him. There's 1 spike that bends back kinda far and you don't get hurt f you put your ship in the slot.)
