It sure is frantic. Got to 3000+ combo with SSS rank by doing literally nothing on the level with two speed fields. Bro just kept boinging from the walls with 90 degree angle and was killing enemies that were spawning all the time. I leveled up like 20 times, went to kill a boss, all of the enemies had no chances against me. Maybe it's too easy, I think it needs some kind of a tactical approach for me to be interesting, like in pool. When you want to change your direction you have to hold a button to slow down gradually, but if you have an enemy on your path (that you cannot see cuz you're too damn fast) you'll come into collision and get hit (cuz you're too slow). Because of that I don't want to change directions and I'm leaving the game in an "autoplay" mode. I think that a time limit could actually be beneficial here, motivating people like me to move! There's a boss to kill! No time to rack up points and levels! Maybe I'm jaded but it's too silly for me.
