I gave it one star on the grounds that it is a game. It has things to do and a soundtrack, and that's pretty much it. I was assembling the robot on the hopes that after I passed the boring part of putting it together I could, maybe, smash something with it, but no. It's a shame, really.
The graphics are good, so is the music track that plays during the game. I'm not sure if it can be considered a game though. You just drag and drop parts in designated locations. It's okay if you want to keep a toddler busy for a few minutes, I suppose.
