It seems like there is now a special prize for getting ALL 576 snowflakes! I'll probably get them all, seeing as I'm doing a bit of cheating (mapping the keyboard controls to a Wiimote NES-style).

@shinesprite How do you map a wii mote to play PC flash games?Please tell? My keyboard platforming skills suck bad.

@shinesprite I don't want to be a bother, but could you bold the the spoiler tags and space out the reward names a little, in hopes of better keeping them a surprise for people? Thanks.

I hate those polar bears, lol. Still easiest level yet, though (took me two tries).

@Luigi Instructions: http://www.kudzuworld.com/blogs/Tech/20070817A.en.aspx
Here is the dongle I bought (comes with Widcom/Broadcom drivers): http://www.amazon.com/IOGEAR-Adapter-bluetooth-Wireless-Techn... True, there are other, cheaper dongles, but bear in mind, IOGEAR includes necessary software.
If you have Windows 7 the process is even easier, but either Widcom/Windows should work on its own.

Once you have the wiimote connected, you will need to run it through Glovepie: http://sites.google.com/site/carlkenner/glovepie This program allows you to map the wiimote to a keyboard, mouse, controller, etc.
Finally, if you want to map it as a controller, you will need Parallel Port Joystick Bus Emulator: http://ppjoy.blogspot.com/
It may be a bit of work, but once you have everything setup, its merely a matter of running your controller script and syncing the wiimote.

Alternatively, you could do what some of the staff do here and get this: http://www.amazon.com/Wii-Classic-Controller-PC-USB-Adapter/d... However the computer will only think of it as a controller.

Finally, if you just want to map a controller you already have, you can use: http://www.xpadder.com/

Got through the three available levels with all the snowflakes, and waiting for more...

The only issues I've had so far are some slowdown, but with my connection it's perfectly understandable; the keyboard controls are tight and smooth...

Joy to Key is a more user friendly controller to PC conversion that works with USB controllers.

So getting all the snowflakes gives you things from the games? I though we would get to play the games?

@Shinesprite and Slapshot. Hey thanks a lot guys .I've been wanting something like that for PC games for ages. Thanks again.

Just passed World 4 with all the crystals and the reward is from Broken Rules (AYIM)...

Level 4 is brutal. Took me a few attempts to finish it with all the snowflakes.

I love this game! Those thin Ice platforms get me every time, though...

Bah, I couldnt DL the stuff from level 4 D:
What is a .rar file? Apperently there isnt an application for opening it... (Im on a mac, so it might not work)

@Supermegaman Use this: http://www.winzip.com/index.htm?sc_cid=go_us_b_search_wz_brand

I rarely handle .rar files, but when I need to, I just download and install the trial version, and uninstall it when I'm done.

I like how they hid the last two snowflakes today. It wasn't THAT hard! The beginning was a bit tough, but at-least they put the hardest part at the beginning of the level!

The 4th level was definitely the hardest.

Level 4 is ridiculously intense for trying to find all the snowflakes. I did it though, just to be rewarded with...a .rar file?! C'mon Broken Rules!

Yes, but I can assure you there will be harder.

Lmao I found a glitch, I jumped of a really high spot and fell through the ground. I could still walk,once the screen hit water it restarted.

This has been a lot of fun so far. The levels are definitely getting harder, but the prizes are also getting better. Just got my level 4 prizes

@Bensen: What's the level 4 reward? I've got it already, but since it's a rar file I haven't bothered to download it...

@Metroid_Fan What's the problem with opening rar files?

And sorry if I spoil this for anyone, but the level 4 prizes are some Wallpapers and two Soundtrack mp3s!

@Bensen: I don't have WinRAR and don't want to bother with downloading it just to open up this one file (I have dial-up, you see)...
