Holger Borum calls puzzle game Alex a "a four dimensional system represented in two dimensions". Reading that admittedly caused me to make my confused Scooby-Doo noise, but it turns out in practice, it's actually not all that mysterious. Maybe a little tricky, but not as bizarre as it sounds. As our blocky hero descends deeper into a series of caves he discovers beneath an idyllic meadow, because everyone knows the first thing you do when you find mysterious holes is throw yourself into them, you use [WASD] to move him around each area... and the [arrow] keys to make him transfer over into the next portion of the grid, aiming for the hole to get to the next level. With me so far? Well, when you start having to deal with, essentially, two versions of the same stage at once with two versions of Alex that move at the same time. Both need to have a clear path to move, and the one on the left uses an opposite control scheme... meaning, [WASD] will transfer him to a new grid square while [arrows] are what moves him around the one he's in. The [spacebar] will cause the two heroes to swap positions.
Confused yet? Well, don't be. As weird as it is to describe, Alex is one of those games where a few seconds of fiddling around will bring clarity even if the game itself actually explains very little. It feels very experimental, with its clever concept and lack of bells and whistles... which isn't necessarily a bad thing, though I could have done with a mute button given how short and annoying the level soundtrack loops are after a while. The level construction is actually a nice blend of simplistic and challenging, but for some players the way it simply sits back and folds its arms, forcing you to figure out the rules and restrictions of movement, is going to be more frustrating than a fun exercise in discovery. Still, it's a good idea even if it feels a little rough around the edges, and if you're looking for the sort of puzzle game that only seems easy and doesn't dress itself up, Alex is well worth checking out.
