Played a few hours. Definitely has its own distinctive flavor when it comes to platform fighters. It does not feel like Smash Bros. and it does not feel like Nickelodeon All-Stars. The closest game that reminds me of the "feel" of this game is Super Smash Bros. Brawl, but the recovery and movement options are very different.

Overall, it seems like a great addition to the genre and it being free-to-play alongside getting heavy investment/support by WB means it will be one to check-in on as time goes by to see how the game evolves, for better or worse.
