A really fun, cute game. My only complaint is that after everything is bought, the game becomes really easy; a rush strategy pours victories. The final boss ended up being one of the easiest battles for me due to this reason; I guess if the idea was as a reward so one could "ride through triumph" this is a good structure.
Okay, when one's on the wall, especially with the sensitivity of wall detection in this game, pressing the opposite direction should not trigger a walljump in the open direction.
Using this game's mileage, each pig is 750 feet long. Since the usual pig is 3 feet long and masses at 60 kg, each of these pigs, if assumed to be at the same density, masses at 9.4*10^8 kg. If pigs could fly, I wouldn't have imagined it would be by far the fattest of the crop.
