Magic Sort: Water Color Puzzle

Overall, I like this game. I haven't played any other water pouring or sorting games, so I can't compare it to others, but it's fun & relaxing. 3 stars b/c there aren't any instructions, or even a "key." I needed a refresher (which tool does what, etc) after taking a couple months off from this game - I looked everywhere, but no luck. It seems they're counting on you remembering everything - or taking notes!

Edit: I was going to improve my rating after it finally recognized I had bought the ad-free setting, but for the past month I've been stuck on level 439, which is either bugged or extremely unclear; the frozen beakers won't unfreeze even when everything else is sorted. I enjoyed this game a lot, so much I decided to pay for the ad-free version. Unfortunately, after I cleared the cache I'm getting ads again, and when I went to pay for it again I'm told I already have it. Really disappointing!

Was a 5-star before today. I grabbed it specifically because it was on Play Pass, so no ads. It plays well, levels are challenging with an easy one here and there, cute, and fun. I've been playing it all the time. Unfortunately with the removal from Play Pass (and subsequent addition of ads), I'll be moving on.
