Managed to find 3 hearts. The game is drop dead gorgeous. Love the neon pixel vibes. Mini
Gravity felt a bit heavy for me? I think I started to get it by the end, but I fell SO quickly that I felt like I had almost no reaction time. Climbing up the slime tower after falling to the secret heart platform took quick a few tries. Or maybe my framerate was too high and that was messing with it somehow? Not sure.
(I am a sicko for HollowKnight and Silksong too, so I'm not just baulking at difficulty).
