I really liked your game! The movement felt responsive and all the gameplay systems worked well together. I love the idea of collecting the souls you need to destroy the demons. The addition of an option to spend souls to revive is neat as well. All the UI worked perfectly on mobile, too. I have one suggestion though: I'm pretty sure citing google images as the source for your art isn't a valid credit. Google helps you find the images, but doesn't actually provide them. You should be able to find the images' sources through google images.
