I think you're making a lot of grammar errors for a very very short paragraph, and that is very very bad. It makes it harder to read, especially harder to take seriously, and for as short as it is, editing would take no more than a few minutes.
For one, you only kinda mention a little of a part of your complaints, as well as your praises. You touch everything once, then pack up and leave. It leaves me with more questions than answers, and reads like a fanboy rant instead of a review. Let's backtrack a bit, and see what we can do.
To start, tell us about the game. For those of us who haven't played Portal (no "s"), tell us that it's a portal-based First-Person-Puzzler with a unique take on the FPS genre. Built on the Source engine, etc. etc.
Secondly, you don't even mention that Still Alive is a 360 game. I'm just guessing that... PSN also has purchasable games, as does the Wii. On that note, what about the users who have Orange Box for the PC, do they not count for this game?
Outside of that, are the puzzles new and interesting? Is it the fact that it's essentially a different-leveled version of Portal that bothers you? If the gameplay's still fun, does it matter?
Also, if I'm not mistaken, $12 is not a bad price for a 60% ranked game.
Too short, even for a "Mini Review," in the sense that it doesn't answer the important question, nor address enough for the reader to make good conclusions from it.
I'd say this whole thing needs a re-write. I shouldn't have more text worth in questions then you have worth of review... I just shouldn't.
