"He's collecting fish!" was the first thing I said when I played this game, let me explain the concept: You're a penguin, you slide down the hill to the finish line, on the way down you collect fish. I know it seems stupid, but maybe you just need to play it, it's free to download so why not give it a shot HERE. I mean this game is the best piece of free software I've ever downloaded.

Gameplay:
I kind of summed up this in the first paragraph. You're basically trying to collect as many fish as you can in the shortest amount of time. The hills vary your speed and going over ice increases your speed, which isn't always a good thing. They strategically place the fish in accordance to the opposite physics of the map, like if you hit an ice patch that makes you take a turn widely, they'll place fish on the inside of the track, quite the challenge.

Graphics:
Eh. Not too bad for free, but not great either. The menus kick ass and so does the background behind the menus. The ice looks pretty sweet, so I enjoy running over that. But maybe it's just how all the backgrounds are the exact same that makes me angry. The penguin himself is well modeled, when he slows down he puts his fins down to the ground, he also makes a trail everywhere he goes.

Sound:
Sweet mother of mercy this is the worst thing ever. I think by the time you play this game ten times (I'm up to 6 right now) you will want to pour Pepsi all over your sound card, then take your speakers and get all the demons inside exorcised. The music is what kills me, the same thing for every map and then the menus are even worse, simply horrible.

Replay:
I'm guessing this is pretty good, I haven't gotten sick of the gameplay itself yet, I'm always trying to top my scores. I think they update it pretty often with new maps, it should help with the replay. The version I have came with about 12 maps, they all vary themselves pretty well from each other.

Summary:
Gameplay - 97
Graphics - 80
Sound - 40
Replay - 75
Total - 70 (Who cares, it's FREE!)
