Some of the best video games are the simplest. This Grapple, a Puzzle Platformer developed by Tuesday Society and published by Midnight City, has no complex backstory, no big end-goal, just jumping from platform to platform.

The player of Grapple is this small ball of black goo. Yeah, I don’t know how to describe it any other way. Actually, I can. Take a piece of Scotch Tape and scrape all the sticky stuff on one side until it forms a ball shape, and then dip that in a bucket of ink.

Anyway, for some reason, there is this ball of dirty rubber cement that is in space, on these metallic platforms that just float there. The object is to get the blob to a portal on the other side, and there are 90 levels of this.

Now here’s the kicker, the ball can jump but it can also stick itself. It sort of shoots out luigis and they stick like those stickable hand things that you get from gumball machines. Again, this is hard to describe.

I will have to say that this game is simple in premise, but it is incredibly difficult in execution. Seriously, you have to WASD to move it, then use the mouse to adjust your view and then mouse click to spit that luigi. When the luigi attaches, you can swing to another platform. You can even use it like Tarzan. It is difficult, but it is very addicting.

In short, I recommend this game. It is available on Steam for about $7.99, but I have heard that it might be available for a limited time for $7.19. It would be a good deal even if it was $9.99.
