Yes.
Update: no speed by decimals.

I see. Nice and creative. Also really hard and challenging. Keep up the good work.

Oh boy, this boss has problems.

For starters, the rock-Rinkas move too quickly for the player to be able to react to them most of the time. The only real way to avoid them is to get lucky. This is especially annoying since the player isn't given any power-ups before the fight begins. Plus, since the boss is just a Mother Brain sprite swap attached to a jumping Para-Koopa, the player can just hold the bricks next to it to damage it multiple times at once, especially once a mushroom is generated and the player can just take a hit while constantly damaging the boss. Also...that's it. There's nothing more to this boss other than what I stated.

If the Rinkas were slower, and this were the boss of a well made level, it would actually be quite enjoyable. But, as it stands now, I'd say this gets a 4.5/10.
