When I first watched the quicklook of this game I thought "yeah it really does seem just like Portal." But I bought it because I really enjoy puzzles games. Now I did a video of the early parts of the game (even earlier than the quicklook), and if you're interest you can watch that here: http://www.youtube.com/watch?v=1g4jgAXbmHU
But once I played further into it, I found it to be very very different from Portal. It does use a lot of the same themes and is structured similarly, but the actual puzzles are quite different. Especially when you get the third dimension. I'm surprised at how much platforming is in this game. Which is kind of cool as it seems to work pretty good. I don't know if there is some soft locking system so that you don't fall off platforms too easily or I'm just some sort of savant but I haven't had much trouble with any of the jumping sections. Aside from the occasional misjump.
Also, the uncle character has soooooo much dialogue. He's almost never not talking. It's kind of amazing how much was written for him.
Are you guys enjoying it? Do you find it's too similar to Kim Swift's other works?
