Thanks to your answer.
I see the starting (higher) platform and the wooden platform I can't reach.
I can't go right.
behind this platform is another platform
on this lower platform, close to the higher platform, there is something that could be flowers or mushrooms that has no effect : I don't bounce on them and if jumping from there, I'm blocked by the "roof", even when trying to manoeuver.
behind the lower platform, there's the ground.
on the ground, close to the lower platform, ther are pink mushrooms that have no effect on my jumps et I don't bounce when landing on them
just right to those pink mushrooms, ther are green mushrooms I can't manage to land on, since everytime I try, no matter how I do, the chararcter lands on the lower platform.
I'll add that whatever game I launch, the first thing I do is trying arrow keys, I won't even try to use the arrow buttons on screen...
I tryed the other available character and I'm tired of fighting dozens of unwinnable fights with the very same opponent. If it's the point of this character to lose, don't make it a game, make it a visual novel.
I don't have access to "gold" characters and I'm not interessed in having it.
