Thank you for your comment!
I already realized that I have some problems with the lvl design, but I won't change it in this game. The maximum I'll add is signs to make players.
In January, I'll try to fix the platforms, because I feel sorry for people after all. I won't be constantly adjusting the camera, but I'll listen to your advice.
This was my first experience with a platformer, so I haven't developed the necessary skills yet. I'll try to develop them for future games
