honestly the mental stuff could be cool as a two way street
maybe some enemys are weak mentaly to females or males or futas eta
or some are weaker to smaller people or giants
you could make a weakness system where all enemys have strengths and weakness if you are their weakness you control them but if your their strength then you basicly get bitch slaped around unless you have something else
id suggest making a rock paper sis style combat
mental - mental is things like looks or words
strength- this is basicly rape tho you could add kinks and one of these could be rape - none con
speed - anyone whos faster has less of a chance to be hit by strength
endurance - while endurance is your overall strength and normaly shown as your hp bar you could add this as a state that increases your hp bar
