A few more minor suggestions...

-I'm begging you, bring back the old style sound effects for power ups! PLEASE! I don't know how I'll survive without that "Noooo!" one when you pick up a No Bat... good times...

-Regarding Cluster Bombs, Popgun pellets and Mines: How about being able to deflect Cluster Bombs and block pellets (but not mines)? If that bat can stop a spinning razor ball, it can take a goddamned pellet. Mines should by definition be unblockable, but that's not a problem right now. Hey, you know what'd be really cool? If you couldn't see the mines at all...

-When Mini mode is on, the Extreme Power meter still shows up normal size. Is it possible to shrink it so it matches the new, smaller player?

Okay, this one's a little more urgent.

So I'm playing grenades, right? I had the grenade on me, and I had to go somewhere, so I paused the game. I got a very unpleasant surprise... I think for shock effect you should try it yourselves.

Another one I've noticed is that Tag stays on you even after all your bubbles are burst and the woodpecker departs the arena. If you pick up a Regenerate, the balloons will start popping as if you were tagged even though the woodpecker has left the arena. I'm not sure if this was intentional or not, although I do think that if all of a player's bubbles are burst, the woodpecker should at least stay in the arena, or fly around the tagged player.

The wood pecker goes away, but it comes back after a while some times.
I personally find tag a little annoying, since it comes up almost every game
and it goes much faster than in airburst one. It should either

A: Be slowed down.
B: Pop balloons only when on the character. It would fly over to a character when they are hit and only begin popping them when its touching, rather than teleporting.

It should also STAY away when it leaves. It only goes away when someones completely popped. It should only come back when another pineapple is touched. Right now it makes Flux disadvantaged since his extreme power just makes more balloons for Tag Bird to pop.
