It’s a reasonably traditional idea – match 5 in this case, by sliding tiles in either vertical or horizontal lines. A bit like in [the game it’s a bit like]. Except here you’re doing it competitively. As you clear tiles you gain powers, which let you do things like fire rockets at other players (either AI or real actual human people), or defend yourself, or open up wormholes – the usual. The demo lets you play one type of game in one mode, but it’s a goodun. And the full version is only $15.
Here’s what it looks like when you play it. You watch this one with your eyes.
