You could still keep this one as a upside-down variation of it.
It still looks cool.
Also could the tilt direction of comets change every wave? However this could apply only for Weekly Challenge.
I don’t if it’s a bug but the mirrored variation of “The Chicken Wobble” the gap at the bottom of the screen is bigger, like the enemies go up earlier.
At the mirrored variation of “Neckties are cool” the enemies the come from the right still appear at the top & enemies that come from the left still appear at the bottom like the original variation, should it be reversed?
