-Bring back the 2 types of Ballgag that was previously on the Prototype of this game
-Dildo gag
-Panty gag with duct tape or cloth
-Nipple clamps
-Vibrator, dildos and crotchrope
-Types of blindfolds, like sleep mask
-Harness gag
-Ring gag
-Tape Mummification (on customization)
-Reverse prayer bondage
-Elbows tied together just like in Bondage Nightmare
-Custom eye and hair colors
-More custom hairs
-Ball tie, frogtie, breast bondage, strappado
-Collars
-Add chains, belts, and handcuffs

I also suggest making a discord server for your games so that we can see updates and suggest too there.
