Okay, what's a good Android game that's simple but still, like, visually pleasing and not totally frustrating?

Okay, so I was looking for something to play on my commute that wasn't another match-three nightmare, and I stumbled upon The Falling Ball Game. First off, the color choices? *Chef's kiss*. The whole aesthetic is just really calming, which is a major plus when you're crammed on the SkyTrain. The gameplay itself is simple – you're basically guiding a ball down, avoiding obstacles. But the thoughtful UX is what got me hooked. The way the difficulty ramps up is perfect; it's challenging enough to keep you engaged, but not so hard that you want to throw your phone across the room. Plus, the haptic feedback is subtle but effective, adding to the overall experience. I also appreciate that it doesn't bombard you with ads every five seconds. Seriously, if you're looking for a chill, design-forward game to zone out with, this is it.
