Hide the restraints (Patreon)

The Hard version will be released after August. Excuse me, but I can't answer questions about release dates. Thanks for your understanding.

Added the setting to hide the restraints. It's displayed as "None" on the stage setting screen like this. 

However, it only hides, but does not change any other behavior or anything else. When hanging, it'll feel like floating in the air.
This is because some of you may think it's better to be without it and I should pay attention to such expressions when posting images in the places like this.
Originally, the reason there's restraints in this game is because I have to move her limbs
if without it ^^;
