Good thing I came back here after playing through all the endings. Number 4 was the one that eluded me, and it seems it's because it's the only option that had an ending already. Going to play the other games you have here.
Would love to see more games with the bunny guy and the squirrel gal. Heh- even a game with the bunny guy and the dude that shows up in the sauna as well.
