No. If you read my previous post- I'm only using this CONCEPT art to give an IDEA of how the 3D bosses could work on a 2D plain, both in attack pattern and look. Anybody can pick them up and incorporate new art elements into them. I've only just started contributing to this thread. Go back and you can see Synchroniser and Titan's excellent art/drawings for the zones and there are also some other admittedly decent badnik/gimmick sprites contributed by other people. However, saying that when it comes down to the bosses I am actually being a tad serious. I'm no hacker but from beta edition hacks I've played it seems easier for programmers to incorporate previous Sonic game elements before going on to create their own. So, if this is ever going to get off the ground for now some people may just have to except the first edition isn't going to be amazing. Never-the-less, if you wish I could ask Titan to send me his level designs and then incorporate the concept bosses I've designed into them.
