I'm not really into puzzle games. But, with a solid story and great gameplay, you'll definitely get hooked on this one.
The gameplay is simple, but complex at the same time. There are many cutscenes, with the option to skip them. But it mostly consists of being at a bar and drinking, and climbing lots and lots of blocks. At the bar, you talk to friends, other patrons there, and drink. The more you drink, the faster you can move and climb the blocks. Sounds easy? Well, trust me, it isn't.
You receive text messages from both your current girlfriend and your blonde seductress, and can choose how to respond, which affects a meter. Although it changes how Vincent thinks in the game, it really has barely any impact on the story.
Vincent controls fairly well in the game. You have to move and manipulate blocks in order to climb the walls fast and furious, because the blocks are crumbling underneath you. There are numerous power-ups, from energy drinks which let you climb two blocks at once, create an extra block, and enemy eliminators. However, Vincent's control isn't perfect, he is extremely stiff at times, and with the wall he climbs on a 3D plane, the camera isn't the greatest. It can't pan around the entire tower, only about half way. So you have to sometimes take leaps of faith on the other side of a wall in order to progress, and in the later levels, it can get nerve racking.
But, overall, it's a great game, and you really should pick it up. With lots of practice you should be able to scale these walls with ease. It's also an interesting game to play with your significant other just to see some of the decisions they make during the story.
