It is a beautiful game, very calm colours, and lovely concepts. There are however a few things that would make it more useful. First, a mindful game maybe isn’t really about ‘winning’. There are lots of cooperative games these days, and this is a missed opportunity to create a game that doesn’t involve competing with your family and siblings.
Also, it is essentially snakes and ladders - but if you have a kid who has lots of passion and needs the mindfulness, they might struggle with the idea of going backwards, losing a turn etc. and it is all pure luck, so parents can’t even make it ‘easier’ for the youngest children.
The ‘Happy Cards’ are my favourite part, however they make it hard to play regularly as they are often asking for your ‘favourite’ something, or ‘the best’ something, rather than just ‘tell me about a wonderful memory’. The second would allow a different answer each time rather than the same one.
Also, a great addition would be additional mindful techniques - such as describing things you hear/see/smell etc.
