I absolutely agree with you! There's just a certain charm to these stages and their early 3D aesthetics with the flat polygons and the wireframes on secondary runs of the stages after obtaining all the Chaos Rings. It was an intermediary of what was to come with the Sega Saturn. It makes me want to see what a Retro Engine version of these would look like getting the same treatment as Sonic 2’s special stages. There’s this flash (R.I.P.) game called Run 3 that reminds me of these stages too. I’ve also been enamored with a certain piece of fan art that combines the special stages of all the Genesis trilogy games into one and uses the Chaotix stage as the centerpiece of it where Sonic is running. The art was made by Liris-san: Source: https://www.deviantart.com/liris-san/art/The-Frontier-World-Warps-of-Confusion-469026556 I played Chaotix a long time ago so I may or may not be correct in this but I recall that if you aren’t able to collect all the required amount of blue spheres it doesn’t actually kick you out in failure and will instead just lap over the stage again for the missing spheres. Just as long as you had enough rings you could keep going just like you said. I really do find that to be a great incentive to keep as many rings as possible by the end of an act. I found that to be a great way to handle it.
