Ending 1: Get no puppies and just fly away immediately. Ending 2: Get fewer than half the puppies. Ending 3: Get more than half the puppies but don't beat the boss. Ending 4: Beat the boss.
I wanna know if there are any more. So for anyone reading this, after you get inside the general's chamber there's a cat. Try defeating the general and escaping without getting the cat, and see if the cat still shows up in the ending.
i think there are 7 different endings, but I'm not completely sure.
ending 1: get no puppies ending 2: get less then half the puppies ending 3: get more than half the puppies ending 4: get all the puppies (not sure) and don't beat boss ending 5: get all puppies, get cat and beat boss ending 6: get all puppies, don't get cat and beat boss ending 7: get all puppies get cat but don't beat boss
(I'm guessing number 7, but it seems possible because the planet explodes if u beat the boss and get to the ending with the cat, but not sure if it would still explode without the boss but with the cat.)
