I'm digging this game a lot if just for the atmosphere, graphics, and music. It's also really fun to play and can sometimes be tricky to get all the gems.
No qualms with the controls myself, but unlike with DuckTales: Remastered, I'm not familiar enough with the original to bitch about them. Though what little I have played, the Genesis game is a little unforgiving with its controls, and the floaty nature of the remake kinda works nicely.
