First off, this will likely appeal only to casual gamers. Indiegala is currently having a sale and they have three puzzle games in the Quell series for just A$0.63 each. They are:
Quell https://www.indiegala.com/store/game/quell/344480
Quell Reflect https://www.indiegala.com/store/game/quell-reflect/348430
Quell Memento https://www.indiegala.com/store/game/quell-memento/348440
These games are redeemed via Steam and currently sell for A$5.95 each on that platform, so this is an absolute bargain. In addition, all purchases on the Indiegala store at the moment get a free scratchie for a random game (I got "Epic Showdown" as my freebie).
These are great puzzle games. I wouldn't call them casual.. Later levels are harder than that.
I'd really prefer them on mobile tho.
Iirc memento tries to introduce new elements which kinda makes the magic gameplay disappear. Try the earlier games.
