Gave Helldiver's 2 a whirl but it's shitty with MKB. If you're willing to play a shooter with a controller it's probably pretty good.
DRG Survivors is fun but my first autoshooter, so kind of weird. Great to play with one hand tho. This one I do play with a gamepad ha
I think the dance dance revolution mechanic is trash, but I could accept it more with a gamepad. And the movement and animation is absolutely intended for an analog stick, so when that translates to a "D-pad" (wasd) it feels janky. But I haven't actually played it with a gamepad so I really can't say, but I think it's not good on kbm.
