SlipSlide (Apersoniguess)

Slipslide is a colourful puzzle game which has you, as a box, trying to get to the end while avoiding obstacles. Experience 25 different levels in five different world, each level and world being unique in their own way. Additionally, for a minimum of $1 (I tried to make is $0.49), you can download a .zip file containing the source code and raw HTML file.
