This is a really good game with even more potential. I would suggest tweaking the layouts to add more action while still keeping the idea of the 3D layouts, and possibly adding some unique elements to the background to make different areas more unique. That's not to say that the game looks bad, quite the opposite: it has stunning pixel art! It's only that the stages, especially the Classic Sonic stages, feel a bit empty. The 3D game's Zones took advantage of the 3D space, and were designed for the 3D space (even the Classic levels) so there's not always much to catch your eye in this form. The level designs in this game closely emulate those of the 3D game, which I think has some issues. The game runs at a snail's pace for me, and that might be my laptop so I'll overlook that, but there are some smaller problems like the hitboxes for certain objects not being big enough (I ran past the Goal Ring but didn't finish the stage because the hitbox was too small, and I missed some rings for the same reason), slightly off physics for the characters and enemies being a little uncommon. It's fun to play and looks great! There are many issues, however. Strange, isn't it So I want a new mod that makes super sonic MUCH better.

Also for classic super sonic, you don't get any higher speed or jump higher. This is a really good looking Sonic fangame. So in sonic generations, when we have super sonic skill and go super, we lose 2 rings per sec, and you lose 7 rings per sec when you boost.
