The level designs are simplified compared to the Genesis counterpart, which is to be expected for the Game Gear. But surprisingly swinging from pole to pole felt more fluid/easier and you have more control over where Ristar goes when flying. I also really liked that you can pick up some weapons dropped by enemies and use them.
Take the graphics and level design of the Genesis and the easier controls and more tools to grab/use of the Game Gear and there could have been a really good sequel.
