If you briefly describe the new part, then it is head and shoulders above its predecessor. The mental worlds are even more diverse – the level design has become even more insane, the characters are humorous with or without reason, the plot with sharp turns does not make it possible to get bored even for a minute.
Battles with huge bosses and just with all living creatures have not gone away and have become more sophisticated. You can laugh for a long time from most of the dialogues and replicas of the characters, their movements, and simply from their ridiculous faces.
We will still be engaged in collecting all sorts of emotional and mental pieces of puzzles – that is, a banal search for everything and everyone in order to collect all the elements that are hidden. Choo-Choo Charles 2 immediately interested me with its “madness”. In the finale, we must fight the antagonist, who has to be awakened in the story in order to get rid of him once and for all.
