I only found 5/9 coins in the Tropics/Stairstepper level. Tried every character and every door several times, saw walkthroughs but apparently the leven changed, since it had a lot more coins back on 2010.
This makes impossible for me to keep going, it's the last star i need to use the cannon in the credits. PLEASE HELP ME! thanks
