I didn't have any previous experience with this aside from knowing that it is pretty well-regarded. It's certainly capable! But I feel like this level of quality should really be the bare minimum expectation for a platformer, even in the early 16-bit days. Good difficulty curve, solid mechanics, polished look. Nothing particularly inspired going on, though.

You can see touches of some of Sega's other Genesis games like GHOSTBUSTERS and SONIC in here, but this doesn't really touch those at all, let alone any of the other big boys from this period.

Mickey does have an all-timer of a walk cycle in this though, gotta say.
