Hey SleepyKirby, thanks for playing the game. If I recall correctly, the B ending is gotten by not having all the keys by the end of the game, its one of the more tame/bad endings.
No problem! It's just that the fishing really hurt my hands while playing because of how much I was button mashing. I was just pressing the arrow keys, A and D like crazy! I almost got carpal tunnel when I finished the game. Also while playing the pallets did not work. Whenever I pressed CTRL the game gave me a error message and then crashed.
