I really like the idea of using the altfire to discard your weapon, and of having a star be dropped that someone else could pick up; that sounds pretty cool! Maybe the star should only come out when people discard it on purpose with the altfire, though (if that's possible), instead of any time you change powers.
For Hyper, would there be a way to make it work simultaneously with the player's previous weapon, or would it work better to just have it be a separate weapon entirely? Also, it might be neat to have it so that when you run through people with it, they fly off in Wind Storm/Old Gravity Hold fashion.
Also also, I think that having a visible sword/hammer/star rod for the weapons where that would be applicable would be a really good idea as well, if people could make it work without inducing a whole lot of lag.
Manibogi, I do think the green frames look cool, but I would probably support your using the blue ones, since not having blue on the hurt frames might bother some players...
And, Sora, I'll put you down for Bomber then. Looks... uh... good so far! Thanks!
Also also also, I was thinking about it, and I realized that there's a clearer, less ambiguous way to lay out the whole weapons thing into three separate questions (though some options kind of preclude the others):
1) Should the powers be implemented as weapons, or morphing classes?
2) Should the player have multiple weapons usable simultaneously, or just one?
3) If just one, should the player equip the power immediately upon pickup, or be able to hold on to multiple powers in reserve, as Proto/Bass Buster items?
Immediate pickup seems a little restrictive, but it might also allow for cool stuff, like those Sleep-filled trap rooms from the games, as well.

Anyways, I think the consensus so far seems to be pretty universal for weapons, rather than classes, for having one weapon at a time, and for the ability holding weapons in reserve
I think... So unless there is a lot of disagreement suddenly, we may not need a poll after all.
If someone could make up a Kirby hand and some weapon/health meters for the HUD (since we'll probably have those any way we go), I can add them to the first post for weapon designers to use. Does anyone have ideas about the weapons icons? I don't know how flexible the Skulltag HUDs can be.
