This new Hydroid looks more efficient, also a lot more visually boring to play. The tentacles flailing enemies and becoming a puddle were things that I always loved from his design. As some have mentioned in other comments, I'd like the puddle to survive (as an augment or as a crouching mechanic) and you could keep the tentacle flail If you make a damage tentacle = damage enemy thing or even cooler damage kraken = damage all flailing enemies.
