I actually have, and they are pretty fun! I stumbled upon one recently, and it was quite an interesting experience. It's a game called
tower rush, and the concept is quite straightforward but addictive. You basically try to climb a tower, picking safe spots as you go. It’s got a good mix of luck and strategy, which keeps things exciting. The visuals were also pretty slick on the version I played, and it ran smoothly on my phone too, which is a big plus.
