First of really appreciate the feedback

I wonder should the effects of the "mess up your controls" potion be temporary or permanent until stunned?
It's permanent right now (0.5.1.1). If it was on a timer; people would stand still at much as passably, and I really don't see Spelunky as a stand still and do nothing game.
I think I'm going to lessen the effect, right now there is no choice; when confused go to a high place and jump! If the effect was less shuffle and more reversing, like left to right or jump to whip. You could decide to keep it, until stunned (that way not losing a life to nothing) or "cancel stun" it in fear of falling in to spikes or just losing life to non stunning enemies.
I think -5 health to +1 health isn't really a good tradeoff. Maybe, if getting that bad potion, you can avoid the worst of it, but you'd have to be quick somehow.
It's not really -5 life to +1 life, but to negate the dmg. from any attack (even instant death). But -5 life really isn't that great, I'm going to change it to 4 life over 2 minutes (even over lvl ends), so if on full life (4) you have 2 minutes to get 1 life without losing any.
Maybe put in a 3 lvl passed until effect removed, or a cancel system; if under a negative effect from a red potion a black potion would have no effect, but will cancel the effect of the red potion. Black cancel red, green cancel black and red cancel green.
Using potions on others isn't very intuitive I think it should either always work on whatever it's thrown at regardless of target's state consciousness or by "buying" a potion while carrying someone.
Also bubble should work on others maybe confuse should too at least visually.
Making water cure confusion could be nice.
There should be some sound effect for drinking potions.
Full bottles don't break but empty ones do? I might want to refill that empty bottle!
The first version had enemies drinking on contact, but you really don't what to lose a potion because it touches a enemy, when dropped for any reason. Also when was the last time you trowed a beer on some one? Did he drink it on contact?

water dispelling confusion it pretty nice

really likes the idea of bottles being refill, maybe you could mix potions to make another; if mixing green and black you get red?
