Oh, I see! I'll have to try that out then.
I feel like, if you want to expand on the endings more and make a no-damange ending, it'd make sense for there to be an ending with partial corruption for being partially but not fully suited, and an uncorrupted one for if you just got your clothes damaged, but not damaged enough for any slime to get on your body, and that second one could be the "no damage" ending, and have it still be a bit more achievable for people who don't want to miss out on the scenes. And then you could make a slight alteration of that for the damageless ending with a congrats message so people who no-hit it could feel special. I don't know if that'd be too much work, but to me, adding an ending with unique art just for the very difficult no-hit (that you yourself admit the game isn't designed around, no less) seems unfair to those who would want to see your art but don't want to take on that massive challenge.
