The music was honestly epic and for some reason felt so great flying around, I felt like I was playing Rayman in a way! The controls felt slick, I'd love more feedback from things like checkpoints, which I only realized was a checkpoint when I died. I was trying to fly into it for a while because I thought it was a pick up! Maybe some UI text to say something like Checkpoint set!
Nice work all around! Love me a metroidvania I do!
