Great puzzle, took me a bit longer than most 2-star puzzles but really satisfying to solve. Even with a bunch of digits in I still had to think a lot which I really like.

Beautiful setting, fresh logic, excellent symmetry and aesthetics. The combination of the thermo and the loop constraints result in unique flow in the puzzle. Thank you !
MSDOS: Thanks so much for the comment puma17! I'm glad you liked it!

inspired by parcheesi? great puzzle!
MSDOS: Hey thanks! It was actually inspired by QR codes, but I can see the resemblence of the long loop to parcheesi!

Really fun puzzle. Enjoyed the thermo loops constraint, hadn’t seen that before! Puzzle had a really nice flow to it!
MSDOS: Glad you enjoyed the constraint! I hadn't seen it either, but I think there's a lot that can be done with it.

Great puzzle! It looked like it would be simple but then it wasn't. And the visuals are very well done.
MSDOS: Thanks so much softie!

This is a gem! Such a blast to sort through, not too imposing, and novel enough to feel very fresh. Great setting. Great puzzle. Bravo!
MSDOS: Thanks so much for the kind comment, it means a lot!
