Very nice! Definitely gave me that "one more play" feeling, especially on the jelly cube massacre stage. You got a lot of mileage out of the sprite x/y squishing animation--I'll have to "borrow" that technique at some point. =)
Highlighting characters was tricky. I think I would've skipped the isometric circle in favor of a player-facing rectangular lasso. In particular, the circle grew strangely if you started it near the bottom of the screen.
My frenetic clicks to move the party out of harm's way were often interpreted as drags, deselecting the whole group just in time to get nailed by an enemy. I'd suggest increasing the minimum drag distance to start a new lasso, or leave the current highlighting intact until a new lasso touches the first character. Whatever RTS games usually do.
The shadows were immensely helpful in figuring out where a sprite was in relation to the party, but I think the mana/hp/xp balls should have bigger hitboxes or lie on the ground. Sometimes a ball would pass through my entire party even though the sprites touched.
On the whole, this is a great HTML5 example. Congrats for designing & cobbling it together so quickly.
