itch.io

game doesn't launch for me, there is a flicker of it opening but a blink is slower than the flicker before it closes. 

Can't play(Android only) but a good way to spice things up is to add a shady character/other demoness that will give you other abilities like x-ray and trance(let's you grope and eventually undress girls without reaction) in return for favors and information about your contractor that could lead to you gaining some control of your contract(either saving your soul or supercharging your existing abilities)

There are options in the top middle of the screen, hit menue and above save should be character, hit that and your inv., stats, perks, etc.. show up(you can only access your items when appropriate)
