For 10-15$, Portal is well worth the money, and the great thing about it, is that it's so simple yet so fun because of
The whole game is surrounded around this portal gun. You shoot portals which you must use to solve puzzles to get to the end of each level. That's it, that's the whole game.
The game is very simple yet the portal gun makes it all great. Getting to shoot Portals is really really cool, and lots of times it's great to just shoot portals and look through them and just be like, "Wow, I'm seeing through that Portal over there," or, "Hey! That's me! I'm in 2 places at once!" The whole Portal concept is amazing and it really makes the game a lot of fun.
The last level is especially good because of the fact that there's actually suspense and mysterious and it really makes you scared in the last level knowing that others are out there and it's only a matter of time before you run into them and that you're about to face the final boss who toys with you constantly throughout the game.
The only problem this game has is the length. The game is literally only 19 levels (though the last level could count as 3 levels it's so long) and each level only takes you about 5-10 minutes to beat. Now I know the game is only 10 dollars, but come on, you could beat the game in about 3 hours, that's WAY too short, that's extremely short, and I don't like it.
There is no music though this is used only to make you feel more isolated, and suspenseful which it does well. The graphics are great, no complaints from me.
The story isn't there but picks up at the last level. I do wish that they had hinted more at the epic last level in the earlier levels and I felt the story just kind of jumped out too fast, and would've liked to see it build up over the levels rather than just all be at the end.
Overall, Portal is one of the games I've had the most fun with. The Portal gun is amazing and makes the game feel incredible and the story is actually very good despite picking up late. It's a must buy and I recommend it for all despite the length. The experience is just that amazing.
Overall Score: 9.25
