Very cute idea for the puzzle, though the scanning near the end was pretty trippy there xd

Very very very nice puzzle ! My first 3 stars solve, spent 2 hours on it and it was totally worth it. Thank you for such a nice time, loved the prime constraint.

Very nicely themed and elegant, not too hard if you're good at scanning (which I'm sadly not)

Beautiful Puzzle! However I also think its more of a 3 Star, but its tough to judge for me. Thanks for the Puzzle anyway!

I really liked it! For me it was more of a 3 stars, but I might be wrong.
Thanks!
