It still doesn't work...
Anyway, I was really stressed and I had to run to my piano lesson, so I didn't have much time! Sorry
Here's the problem:
When I walk to it without key, everything gets black except for Mario and the game freezes.
When the key toutches it itself, the screen turns black and the game freezes.
When Mario and the key toutches it, random stuffs happens...
You hear a spinjump sound and everything gets black and freezes, the screen get's black and freezes, everything except for Mario get's black and freezes, everything except for Mario and the FG freezes, pink colour comes ect.
Also, when Mario and the key toutches it, something above happens.
