It took me some time to complete the steps necessary to download this (via PC) and get it onto my PSP. If that didn't make me feel stupid enough - there was the game to convince me I have misplaced the few brain cells that I'd had the day before.
First off, they don't tell you in the tutorial that pieces are being connected together, automatically - but you will usually need to hit a button to do it in the actual game. Yes, I actually was forced to read the rules - where I also found that you can pause the walking figure while you think your way through it. My figure kept falling through holes or and leaping through the air while I tried to figure out how to rotate the puzzle correctly. D'oh!
If you like puzzles though, you can't beat the pricetag ($10), and the game is so "outside the box" (geeze, I hate that phrase) that it is well worth checking out, IMO.
For that type of game - if the word "type" even applies here - I'd give it a solid 8 out of 10.
