I don't know why, but I love this game. the playfield is hella fun to me, though I understand that it's not traditional or to everyone's taste. I like the space theme, and the bowl of the playfield works with the gravitational play concept.
I grew up with this game, so admittedly I'm a bit biased. But managing the clock is a lot of fun, and promotes shot skills. I'm not a fan of the line art, but that's more of a generational thing and certainly many machines of that era had similar style. The color combinations work well. I've always thought the name was a great double entandre. It's very different gameplay than games today, but the conceit of managing the clock is well executed here.
