Really didn't go much on this one. Sure the controls and physics were good but there were too many fundamental problems that stopped this game from feeling good for me.

First up the level design doesn't follow the standard Classic Sonic rule of fast but difficult top routes and slow but easier bottom routes. Instead it goes for a labyrinth style structure with falling usually dropping you into into a previous part of a stage or a short diversion that brings you back to where you just were. Whilst some people might enjoy this, and it can be considered a good adaptation of the 3D Blast level design to 2D, I just found this frustrating.

Second is enemy placement. There were a lot of times where I would get blindsided by an enemy that is hard to react to in time. Now normally this wouldn't be a problem as enemies like that are usually placed in areas where you should be rolling and that will take care of them, but this game also places those types of enemies on slopes going upwards, where you would likely be running not rolling. It isn't even easy to slow down to avoid these enemies as you will struggle to keep the momentum needed to get up the hill.

My third and final problem is the bosses, a lot of them have attack patterns that are hard to predict and very short windows of opportunity where you can get an attack in, leading to a lot of lost rings and lost lives. Sometimes I would even get rebounded into the bosses attacks after a successful hit of my own.
