Listen I am all for short games, but when I am able to beat all difficulties (and see all the levels) in 4 hours it's too short. Especially for a retail title. The game itself is fun but there wasn't a lot of game to play.
Genuinely one of the best platform fighters ever made, but it will never get its flowers because the first game was that underwhelming (also some weird roster choices). Slime meter is one of the best mechanics added to the formula.
"This fucking sucks actually," literally the coolest thing ever in video game form. Not all of it's ideas stick the landing, but the sword is super fun.
