I do not even know what to say. There's nothing to add.

Thank you for explaining, we will try to balance the levels a bit more then. The rain doesn't effect the way ball slides on a surface, it is the same on the all surfaces. Adding more checkpoints would probably decrease the difficulty, we do agree. Could we talk in the chat? We would love to hear more.

Let me explain.
Starting at level 22, the game becomes incredibly difficult.
The ball constantly slides on a slippery surface from the constant rain and becomes absolutely uncontrollable even on the joystick. Not to mention the keyboard.
The ball is large and has a lot of inertia. In addition, the contact spot is not visible on narrow rails and it is difficult to determine where it is located, which leads to permanent falls.
You can fix it by removing rain, expanding the wooden walkways and lowering the difficulty level. In addition, you need to make more checkpoints.

With physics clearly overdone.
In process of complicating the game process, interest to the game itself is lost and it becomes boring, banal and uninteresting for walkthrough.

Hey Demitr,

very sorry to hear that, could you please let us know what is the problem so we could fix it and maybe change your opinion? Once again, we're very sorry.
