I had Pepsi Man for the Playstation and played it a lot as a child, and this game gives me so much nostalgia!
If you like running games, you will enjoy this game.
The aesthetics and music are great, there are gates that change the colore theme of the environent (thus far I do not think it has any actual gameplay effect). The music selection is very good and pumps you up very well. The color theme for the main menu can be changed, which was a nice touch. You have the option of changing your robot character's skin from metallic to wired (to make it match the environment better), and you can also change the point of view from third-person to first-person - I highly recommend first-person to add to the intensity.
The gameplay consists of you running from point A to B without falling off the track or hitting objects (restarting you at the last checkpoint). You also must collect x batteries in some of the game variants, or else you will have to restart. The control scheme is very simple, and the learning curve is minimal; however, the difficulty progresses at a reasonable rate to keep you challenged.
There are a few different game variants - there is an Endless mode where you just run as far/long as you can, and campaign consists of: a Free mode much like Pepsi Man, where you control your character and have to collect a minimum number of batteries to progress to the next stage; a Drag mode where you are just running in a straight line and must complete it within a time limit (you have to time your spacebar presses accordingly); and a Track mode, where you can move freely onto one of three tracks (this is how Endless mode is also played). Track mode also prevents you from doing things like bunny hopping off the side of the track and landing back on it in order to avoid difficult obstacles (this is actually a mechanic in Free mode).
The beginning stages offer quick, simple tutorials to help you speed through the game.
Overall, if you like straight running games, pick this one up.
