For the first suggestion, i would add the options to change the key binding of different actions at future version so player can decide themself.
I understand your point on the item limit. Originally, I limit the backpack capacity by the numbers of slot, and hope to modify the slot numbers by equipment. However, it is not easy to handle to relative change for me. Weight system would be good option for me to try. Also, I may allow the backpack (equipment) to increase the weight capacity.
Sleeping and masturbate are other things that i will implement in the future, but I do really like the idea of sleeping in a location that contain enemies lol. I will see if i can arrange it. For now, i may add the horny decrease and the orgasm things before adding masturbation.
I am working on the new clothing currently and added some color version of long socks already. More clothing are on the way :)
Finally, thanks for your suggestions!
