I forgot the entropy for the first 10 minutes hahaha What a beautiful gift that unwraps so beautifully!

It seems difficult to start then it’s loads of fun.

Took a bit for me to figure out how to start this one. Once I did it was a fast and simple solve. Great puzzle!

Found it more useful to mark parity than entropy, which is uncommon for high-entropy puzzles. Neat!

Easier than it looks, just ask the right questions. A true 1 star gem

Very nice - 35 minutes for me so I would increase the difficulty to 2 stars. Fun colouring adventure though.
