An enjoyable camp space adventure. I didn't need any maths to solve the puzzles. If you're stumped, just experiment a bit and notice what happens. I found writing details down in a notebook helped a lot. If you bypass the puzzles you can finish in an hour, but if you stick at it with no hints, expect many more hours puzzling it out and taking breaks, then going back again with new ideas to try.
I am now off to try the author's other Galaxy Jones games!
