Scratch

General
Ride on charging missiles, race in the "Walk of life", swim with a giant whale and enjoy a prequel to the successful Rayman 2, that tries it's best to immitate as much as possible whilst being a unique game of it's own.

   Original Demo
http://scratch.mit.edu/projects/Borrego6165/2355963
Play the demo which was released over four months ago (it was re-released to fix some bugs, which is why the timer reset). It is a chinese-styled level, which is similar to the final design of level 2 from the official game. However, the technology has far enhanced since then, and on the demo you can see old bugs like multiple-raymans and even see him completely disappearing. Playing the official game for the first level will let you see all of the improvements made.

   Official Game

The official game can be played, but it is still in active development. However, it has less glitches and bugs than the demo, and you can no longer see multiple Raymans on screen, nor does he disappear unintentionally. The scripting has been greatly enhanced since the BETA demo, so it might be worth while to still have a go and play this version.
