I did like how the glide mushroom can help you dodge her swipe-up laser. I noticed that. : ] Also Momo's Blofeld mechanic with the cat is fun.
Switching from a weapon to a health item felt kind of clunky IMO ("What is this, Zelda from before they invented good game controls?" : P), but then again I don't game primarily on PC. Maybe if I'd been using my controller I'd have gotten the muscle memory under control better.
