Are you trying to drag a heart to the girl on the right?
Hearts drops from enemies. You need to drag them with mouse.
Or maybe it's a bug and the sprite hasn't changed. Have you gotten buffs or debuffs from hearts?
Oh... It's definitely a bug. I'll fix it today!
Yes, of course it's just a placeholder. Which rewards do you prefer?
I'm planning to make just a pool of animations. Or something like a visual novel where you're talking with the demon.
One more option is an erotic mini-game where you can make some manipulations with the restrained demon girl.
Thank you! Glad to hear it!
