Awuf!
To unlock toys, you need to:
1) open them in the menu, having collected the required number of love points
2) Prepare Lisa, namely: remove her blanket and clothes (for beads and plugs. The vibrator can be used through clothes)
3) Lift her legs(you can see this in the instructions, click on the question mark in the scene)
4) click on the desired zone of the Lisa with a certain toy.
For example, the vibrator only works between her legs, and it is not difficult to guess where the anal beads and plug will work:)
But if you do all this, but the toys specifically do not work, then let me know, and we will try to figure it out!
