Here's one I just thought about

> Cursed Magnet

#0

Items in the shop will be free.

But, picking up shinies hurts you (shinies will be attracted to you).

Tsughos is feeling very hungry and faint, and now Japes is being forced to help her. (Should have read the fine print of that contract)

Now with difficulty settings. 

Easy: Max HP is 100, the goal is 100

Medium: Max HP is 70, the goal is 150

Hard: Max HP is 40, the goal is 200

How to play: Tsughos will be at the center of the arena, she will not move from her spot, her HP will start at 1. In order to win, you have to feed her until her HP is equal or higher than the goal. (She also cannot be stunned in this mode)

And what are you going to feed her, you ask? Don't be silly, it's you, of course.

The other ghosts (jealous of Tsughos plan, I'm sure) will constantly try to grab you for themselves. 

Saw this thread and decided to give it a shot...

> Engagement Ring

#550 (every subsequent purchase increases the price)

Requirements: Must have Endosomatic Heart purchased

The species of the last befriended ghost will heal you when they eat you.

However, the item will be lost if the ghost is flashed.

There is also a 2% chance of triggering an instant gameover (with a special cutscene) when you're eaten by the befriended ghost.

Not sure about the patreon version but... not everyone has a 4k monitor to play this game, I use a basic monitor and the gameUI is broken on my screen. You should tweak the game to run in lower resolutions
