Epic Mickey 2 isn't a bad game, but you should rather play the first part.
But first the positive: The dyeing / thinning is just as good as implemented in the predecessor. Even decisions made with it, how opponents kill or join forces, remained the same. Fortunately, you can return to the levels to catch up on any areas. A good improvement, as you had to collect everything in the previous game in the first attempt, otherwise you had to replay the entire game. The costumes are a nice decorative element, which always has small useful bonus effects.
Fortunately, the film projectors stayed the same. The intermediate travel in old Mickey Mouse cartoons also creates a good mood in the sequel. A very good voice output was also added to the part. The bosses are good too. The partner system ... is there. It's nothing special, but it's not particularly annoying either.

But what really bothers me is the need to create a successor.
The story has little / no depth. It's a detective story where Mickey and Oswald want to find out where the earthquakes that are destroying the city are coming from.
In the end, in the end, we find out who is responsible and that's the end. What sounds like little is also little. The game is much shorter than its predecessor and creates neither an exciting, gripping atmosphere nor character depth, as it was in the predecessor. So I lack an important drive to play this game.
Personally, I also find the environment more boring than in the previous version. Everything is a bit more colorful and everything looks nice, but the very dark atmosphere doesn't come into its own because of the story and the surroundings, among other things.

So I can say who doesn't mind the story, atmosphere, character depth, more interesting environment and (unfortunately like in the predecessor) muddy textures, can play the part, because everything is solved equally well or even better from a gameplay point of view, but for that other screws suffers.
Therefore everyone has to determine it for themselves.
I've finished.

It's not like the game is unplayable.
But the game has technical problems everywhere, be it that everything is strangely dark except for the characters and some surrounding objects. You can often look out of the map, etc.
The reset points also rarely jump, which means you can often skip stretch sections.
There are also no animations.
If you want to get the game, you should get it on a different platform than Steam, since the rest of the game, such as music, speakers and driving behavior, are solid.
