This game does NOT hold your hand at all. That's not necessarily a bad thing, but there are some things in this game that would have greatly benefited from some form of explanation. It's absolutely playable, but before it becomes playable, you'll find yourself having to go through a lot of trial and error as you figure out how to play the game.
Annoyingly, you may also find yourself running some bug tests just to understand why certain mechanics aren't working. For instance, when a new core/battery (whatever they're called) is finally delivered, and you swap the old one for the new one, make sure the old and new cores do NOT come in contact with one another. For some reason the new core will immediately be zapped of all of its charge when it touches the old dead core that needs replacing. This essentially kills any good run you may have had. So be sure to keep them as far apart as possible when swapping them.
I feel the game actually has a pretty solid base to build on, but it has some pretty annoying issues that I feel could really turn a lot of players away. If you're willing to stick through the trial and error to learn the mechanics of the game, there can be some real fun here.
