Been playing this series my whole life, this series is goated af.
My only complaint about the collection is that they made Recoded a movie rather than actually remastering it and giving us that amazing combat in HD.

This is genuinely one of the best platformers of all time imo and my personal favorite of the genre.
Every character is unique and they all have cool tech they can pull off that feels great; you can basically play pretty much any character with a nonstop momentum and as a result every character is also super fun to try and speedrun if you're into that kind of thing.
Plague Knight is easily my favorite of the playable cast because if you can learn how to chain together your bomb jumps you can just fly through the level super fluidly and quickly and it's insanely satisfying to do right, but the bomb jumps tend to be a little chaotic so you really have to get a feel for them before you get to that point.
Difficulty can spike here and there, but you can die infinite times so if you can't beat the game it says more about you than the difficulty imo
The music is pretty fire too, you'll be bobbing your head or humming along pretty much the entire time.
Would 100% recommend on a sale, but if you like platformers or even retro style games and haven't played this one yet it's definitely worth full price if you're even slightly interested.
