Seeing these new unused sprites is amazing, it's incredible to see something like this being showcased decades later. I love the designs of the enemies and the Robotnik boss looks very interesting. At first thought I imagined that vehicle was originally designed for Robotnik to participate in the race with Metal Sonic (perhaps he could have stayed behind or ahead of the race). However, knowing that this is from the R2 level just makes it more intriguing. Thanks for the great post Taxman. If Sega could somehow get the original development team for Sonic CD and Sonic 2 back together to make deluxe versions with all the scrapped ideas added in, it would be incredible (although it will never happen, a fan can dream).
