I have a plan for expanding the restraints gameplay from just having one stage, for example you are armbinded or not, to multiple level, such as armbinder(Lock level 0), armbinder(Lock level 1) or more and you are getting harder to unlock if the lock level of specific restraint gets higher.
Currently we just have cursed items and curse from some magic circles. I will also gonna expand the gameplay with implementing fantasy monsters with cursing or binding skills.
