What is the crowd's opinion of Slydris?

From 3.5 billion comments

I think I felt frustrated with train control (dragging multiple trains over to handle an overcrowding stop, yet them not moving over for some reason, and me losing the map because of it). I guess my rails suck to allow overcrowding shortly after the 1,000-passenger mark in the first place, but either way, I didn't find much motivation to keep striving for an endless high score. And then I figured all the maps would ultimately be the same in a sense, so I just stopped.

It's odd because Slydris could certainly use more variation, too, but that game has still gripped me like no other.

Slydris is essentially turn-based Tetris and is the only Android game that I've reinstalled to play on every single phone I've had, without fail, ever since it came out in 2012.

Both of these can be played in very quick bites of time or at length:

Slydris is the greatest turn-based block puzzler ever made for mobile devices. It's worth every penny.

Jumbline 2 is also great, a word-unscrambling game.
