This game is generally well implemented and has smooth gameplay. You have a machine that lets you switch bodies, and you can switch with quite a few creatures in the game.
But the game is a bit weaker in the story department. You are trying to solve a mystery in a lab, and some people oppose you while some aid you. But as other reviewers noted, you can directly do crazy things around them without them noticing or caring, including setting things on fire, doing crazy and dangerous acrobatics, or even stealing important things as they watch you. Some of this is explained away later, but it is hard to stay motivated.
Otherwise, this is a nice science fiction game of moderate length.
