first of all i cannot buy the plug butt in the xxx store, i dont know if it is some bug or just it wasnt in the beta.
changes imo:
-dialogs: remove the shape of the personwhos talking, instead use the name or the job ("bob: ....." "boss: ...."), try a white font with a black outline, remove the black rectangle of the back.
- gameplay: i cant imagine of a better gameplay, for a beta is so good, i like all that diferents mechanics, i have only miss some sounds effects, like moans, the cum, an sound when the lube is used...
I think that this game can be so good.
wish you luck.
