What is Reddit's opinion of RGB Express?

From 3.5 billion Reddit comments

RGB Express kills a lot of time for me travelling. Crossy Road is addictive too. I've just downloaded Bloq as another puzzle game.

I have a bunch of "older" games still on my phone, which meet that mark.

RGB Express, Mini Metro, Great little Wargame, LONEWOLF (17+) - a Sniper Story, I love Pasta, Fussball Pocket Manager, WordHero.

And i have a few more, but those are not available on the google playstore anymore:
Minigore 2, Nimble Quest, PapaStacker LITE, Little Generals, Tiny Troopers.

RGB Express! it's such a cute fun game

I love RGB Express and keep coming back to it when I want a nice puzzle.

RGB Express is pretty neat.
