I thoroughly enjoyed this game. The music was really chill and fit well, the art was simply beautiful, the use of the limitation was pretty nice, and I liked the scrolling background movement in the back as well. I also love how you balanced the game out by allowing the player to be able to reach in time to save the angel seeing there were so much demons. I had to cut it short at 120 angels recused since it was kind of becoming a bit easy for me. XD
Only thing I have in my opinion are the controls were a bit chunky when it came to turning angles. Also, I would of loved to see a bit more mobs because this game was really interesting. But I seen you had to rush sadly so its fine. Amazing work on the game!
