One of the less-usual games I played on the C-64, and a puzzle platformer not seen before, and rarely done better.
It takes time and perseverance. Some of the puzzles span huge spaces, which can be a challenge since the game switches screens instead of scrolling, but that has been factored into the design and becomes part of the challenge: turn left or right here? Can I pick up enough speed to jump over the next two screens and land where I want to go? Am I sure I'll land where I think I'll land?
Definitely something that requires time, and is not solved in settings of a few minutes, but also a fairly unique gem of a game that absolutely needs to be preserved.
