A huge upgrade over the previous game in terms of content, depth, side content, story, quality of puzzles and pretty much everything! Two things to keep in mind: First, do not miss the tokens, they are missable, make sure to find them in each level before leaving. And second, get your buddy ready, it will get very difficult towards the end and you need good communications to overcome this game and this experiment.

This game requires a friend to play. By the end of it, you won't have a friend to play it with. Jokes aside, great game. Voice acting is pretty rough. Story feels a bit jumpy. Puzzles were great though. Definitely didn't need to use a few hints to get through it, but if we did, I'd say their hint system was great, and doesn't give away too much per hint request.

Very cool game with nice puzzles; kinda short but good story (especially if you complete all the mini games and unlock the extra cutscene

This has been a fun (and sometimes a little challenging) adventure in this trilogy. Voice acting is funny, as it has been in all three games. Fun to experience with a friend
