512 64x baseplates stutters slightly
and while testing things I found out that you can jump without being on the ground, as long as you were on a brick recently, for a weird low sideways hop
edit: clearing the 64x modter one a second freezes a ton at first (96 bricks), but when it's down to the last 8 or so it clears with stutters (instead of BL frozen)
and just hammering the 64x modter makes BL stutter
