A really cool addition to the game, that I think fits well with the current suite of moves and poses available would be an alternate base pose that summons the same structures, but in an alternate orientation. For example, it could summon a wall rotated ninety degrees so that its thin side is facing the player, a pillar laying on its side, a grounded ball, a sideways disc, and maybe have the cube summon ungrounded, with a small amount of upwards momentum, similar to the ball summon. Obviously something like the grounded ball or the ungrounded cube might need to be reworked slightly, but I think that it wouldn't be a radical change that would disrupt the current balance of the game, and would add enough diversity that could provide very interesting opportunities for a lot of creative combos.

I'm not sure exactly what the alternate base pose could be, my first thought was hands horizontally aligned, with one palm face up and the other face down, sort of like a sideways flick.
