There’s this one playable character that doesn’t have to play on the beat but I don’t know if it’s very helpful since the enemies dance each their own way in the rhythm so you would have to pay attention to the rhythm anyway in order to attack and defend.
I like this game. Usually I don’t play a roguelike game many times because I think too much and it’s complex game anyway so it’s time consuming (I have the same problem with Civilization). This game forces you to act fast and not to think too much. And as in other roguelikes the party could stop any moment so you better keep just dancing while it lasts. It’s a bit difficult game at least for me. I have only completed the zone 1 so far.
Of course I don’t know if you would like it. If you can’t stand rhythm games at all then maybe it’s not for you, but staying on the beat is not really the difficult part of the game. The game has very nice soundtrack so it’s fun to dance around killing monsters.
