Quite a challenge for me to get 3 stars on some of the levels. More on that later.
Per email, it runs great on my Samsung Tab-A 10" (low end Android 8 tablet) with Chrome.
It does work on an iPad Gen 7 with Safari. But dragging is really laggy/sluggish and the click sound-effect is absent 95% of the time - when it does play I have a "what was that?" reaction.
