Since it seems everyone wants a good challenge, I have made the "Icy Challenge" in hopes that more challenges will be built. This is a WIP, the detail and some eventing has not been done, and there are a lot of spikes to event, so come by my server and help me out! Anyways heres some pics, This will be improved.
The Spawn Area

Overview of the First part of the Challenge (Bricks sticking out will have their raycasting and collision turned off)

Inside the Underground Maze, this is the first part of the challenge

The Spikes, second part of the challenge, you have to jump from one 1x1x5 to another without falling on the spikes

Thats it for now, but i plan on adding a laser part and some other stuff. Please come by if you can event, because its going to be hard for me to event all those spikes.
