You control both of the twins and can switch back and forth between them. Most things can be done by either twin, but some puzzles can only be solved by using their special powers. (Yes, it sounds a bit silly, but everyone in this game has a secret power. Tim can float a few inches above the ground and Tiffany can talk to animals). This aspect of the game reminded me a bit of Day of the Tentacle; as in DotT, each character has his (or her) own personality. I have to say I could identify more with the ever-sarcastic Tim, but for all I know, some people might actually prefer his terribly naive sister Tiffany who loves all things cute and fluffy and has an exceptional talent for annoying people through her constant use of baby-talk. But then again it's hard to be angry with her... Most of the other characters are very nicely drawn as well, particularly Dr Love, who spends all his time at the bar getting drunk.

The graphics in the game are nice and slightly cartoonish. They're a lot better than you might expect from a freeware game, and so is the music. Unlike most other freeware adventures, Two of a Kind even has a decent length and may actually keep you busy for several hours. Not everything you can interact with in the game serves a purpose, by the way, but I suggest that you try talking to everybody and looking at everything so you don't miss any of the funny comments. For example, you can try letting Tim (who happens to be a KISS fan) talk to Dr Love. Or let Tiffany talk to Fishy. Or let both look at the Rice Girls poster outside the bar.
