Tornado.io is a brazen (and noticeably inferior) copy of the great UFO.io, which in turn is openly inspired by Hole.io, which in turn is a copy of the Donut County concept (inspired by Katamari Damacy). As might be expected, the end result of such a huge amount of shameless copying could be -- shall we say -- improved. But, regardless controlling your tornado in Tornado.io is simple: just slide your finger across the screen to swerve your tornado from one spot to the next. Of course, in order to absorb items scattered in each scene -- remember, you're a tornado -- you'll need to catch them up within your path by passing by closely. What's more confusing is that picking up elements on screen doesn't involve passing directly over them which ends up being less intuitive than you might hope for. Tornado.io is an entertaining online game, which offers an experience that's very similar to UFO.io or Hole.io--only a lot worse. Its only upside is that it has good graphics. And the truth is that the city is identical (exactly the same) to the other games.
