"Kooky" is a great word.
When I played this game as a kid, it seemed impossible to me. It did intrigue me enough to put some initial tokens in, but I didn't walk away happy. It seemed very difficult to me as a kid. At the time, I didn't think it was possible to do well at because the ramps were too steep, even at their shallowest moment.
Compared to a typical coin pusher where the skinner box reward drip is easier to engage with, even if it is less interesting.
Edit: Apparently this game has a colorDMD
