Ok, tips for the hard badge: Don't touch health powerups if you can't help it. They spawn at much lower rates later in the game and you don't need them early in the game. Stay near the surface and eat mostly sailors, they give more points than fish and are easier to get. You can hit boats/ships with your head and your tail, try to get these parts to collide with the front and rear of the boat/ship. You need to hit them with enough upwards or downwards force to hit the sailors off. When you jump up in the air near a ship, flail the mouse around to do spins and whack the ships with your tail. Clustered ships are easy targets.
So in the end i just played again and kept playing until it gave me the badge, which was around 750,000 points. You don't actually have to send your score, just don't let yourself die until you get the badge.
Huh, back when this first got badges i gave up on the hard badge because it just seemed too hard. Now that i come back to it it was actually pretty easy. Though i'm still waiting for the badge to recognize my score...
Man, instead of knifing the target the assassin should just put a ski mask on him and let the trigger happy guards do the work. Then he'll be able to sneak out easily while they're all busy patting themselves on the back.
I find it annoying how when the guards have never seen you, are all on the other side of the compound with walls in-between, you can't use the extraction point because they just found the body.
