Maggie walks out of, and into the frame on the Bridge level. Also, the water part leaves a small gap on the right.
Maggie appears in the frame during the transaction from Bridge to Scrap Brain.
Both of those are because you're viewing in full screen. If you were to download it and view in Flash Viewer, it'd be it's actual size and you wouldnt see it.
Maggie's descent in Scrap Brain seems awfully slow. I realise she may be using her dress as a sort of parachute, but still.
True. I'll speed that up.
Her pause goes on just a tad too long.
She has that, looking up, looking down, WTF?! thing going on. Only its not animated, coz that would mean more sprites. But I agree it was a bit long.
It's 'laid', not 'layed'.
Stupid fingers.

I thought you weren't going to use the spin jump animation?
That was laziness on my part.
The water (both in Tidal Tempest and Bridge) doesn't move. I realise this may be difficult to animate, but generally waves don't stay where they are.

As you said, difficult to animate. I once animated ground (Hydrocity) moving and it took 190 frames.
The last two dialogue boxes between Lisa and Maggie disappear too quickly.
Yeah, I know. I'd sort that out, if I could be bothered.

And again, Lisa and Maggie walk off into the frame.
Again, full screen.
But with that said, not a bad job! I'm looking forward to the next installment.

Now, if you excuse me, I'm off to play Sonic CD...
Hehe. The only reason I can play it is coz of Sonic Gems Collection on GameCube.
