The only thing missing was the potion that makes magic doors.
OK, I have found more coins and secrets (yay) but I am at a complete loss of how to get that one coin in the desert area at the top left. And I can't find any other coins than that one! This is driving me mental; if somone doesn't hint me with what I need to do I might go insane.
Spoiler: (click to show/hide)In area 4 (took the shorcut from area 2 to see if that could help, but it didn't) there is a locked door and no key. What is the point of this?
Spoiler: (click to show/hide)Take the spawner, not the bombs.
Spoiler: (click to show/hide)The room with the double-sized blue bouncer thing and the red bird. You know it I am sure. I have tried several different ways many different times, and I am hoping somone can hint me on what the best route is. Right now I was trying to let go of the bird through the smaller hole then grab it again, but it is proving VERY difficult. I almost had it once, but I had too much down velocity and I fell off the stage. with my bird.
