Fun game! It definitely takes some repeat plays to appreciate the value of the various items, which is just as it should be, and I think I could still learn more with more plays. I played on Medium and had to restart once (instant death respawn situation), but after that was able to use my respawn point to try out different strategies -- and get different demon configurations -- and I was able to make it to the end. The UI works smoothly and intuitively, I enjoyed the music, and I really liked the changing of the seasons in the art. Nice job!
