Awesome game! I really love the art and the sound effects are really nice! My dog who was sleeping on the bed next to me  kept perking up everytime she heard the bark. I love that all the characters have little parachutes. I think if I were to add anything, it would be a revision to the way the level restart works.  It can be really tough to have to start a level completely over because a hog vital to the puzzle just walks off a ledge, or for some reason he parachutes the moment he hits the ground. The solutions are actually very clever for the second and third level! I think finding a way to signal those to the player or making trial and error a bit more forgiving would be the way to go. Great job!

One of my personal favorites so far - a simple mechanic that is used at least 3 different ways. Really polished feel and vivid graphics!

• I spent an enormous amount of time on the boss, partially due to the fact that a) I am never sure which direction piglet will throw itself on, I noticed that when I step away, the pig also steps away in that direction, making aiming really hard and b) With the pigs in ships, I wonder if it makes more sense to aim at the entirety of the ship rather than the pig in the ship. Just really frustrating experiencing in aiming, again.
• Sometimes pigs will just throw themselves off the cliff... considering how they're an "ammo" in the last boss battle, made me restart couple of times.
• In certain cases where you need the pig, I would suggest they respawn after a certain amount of time. Like when you need to be pushed to an island or in the last boss battle. I can imagine much larger levels where losing pigs forever could be very frustrating.

But the game is really fun to play. You game design skills are great!
