The possession is a very unique mechanic! However, I think the lack of feedback really makes it difficult to understand what you're doing. Enemies don't have health bars (understandably so, cuz then you'd confuse them with the bodies), but they also don't recoil when they're damaged or change their sprite to show they're hurt. I found myself worrying, "Does Futo not take damage from this kind of fairy? Are the bullets not connecting?" However, I really do like the visuals, the characters becoming more Fucked Up in their portraits when Mizuchi is possessing them is great.
