This is a great game and a fun way to keep your brain ticking over! I’ve learned new things from playing it and find it really enjoyable and sometimes quite challenging. The only problem I have is just my personal preference - I don’t know if it’s because I’ve hit a certain level or it was from a recent update,but all of a sudden there is a timer on each level. You don’t have to complete the puzzle within the timeframe and can still progress if you ignore it, you just miss out on more rewards with each level and get a few pop ups to bypass it to continue. I’m glad I can still progress without using the timer, but it would be good to have an option to turn this off if you’re like me and just play for fun and to relax. Another tiny annoyance for me is that the hint (and other tools) button is at the bottom of the screen and I sometimes brush it by accident which uses up a hint when I don’t mean to. It would be nice if these buttons were at the top of the screen on each level, but that’s just me! Apart from that I really enjoy it and it has a good amount of variety on each level now than before. Love it!
