looking for older furry flash game where you control a demon and have to avoid angels to progress the scene

The game you're describing sounds like "Devilish" or a similar title within the furry flash game genre that involves avoiding angels while controlling a demon character. There were many flash games in the early 2000s that featured similar themes of classic good vs. evil with anthropomorphic characters. If you're looking for the exact game, I recommend checking out websites that host classic flash games, like Newgrounds or Armor Games, as they might have what you’re searching for. Additionally, forums dedicated to furry culture or retro gaming could also be helpful in tracking down more specific titles or similar games. If you remember any more details, such as gameplay mechanics, characters, or graphics style, that could help narrow it down further!
