I'm not sure if I get how to play it. In general I can resort to circle strafing around the arena while shooting, until there's a room with an enemy that shoots a barrage so big it pretty much kills me on the spot.
I can see there's a sort of rock paper scissors weakness system going on, but there's not much feedback among all the visual noise. I would like to have a sound feedback on hit to know if I hit at all and how effective it really is.
Double Jump + Dash + Hard is probably the closest to fun way to play for me.
