love the game but a few thing that could add more replay abelaty
1. more/ bigger monsters. witch could harm u so it makes the tazer more yous full.
2. upgrade tree. like more the one can breed with u, faster milk perjusion, faster inqbasion exsetera
3. giving birth/ more slots so not just milking fresilaty but breeding so it could become a farm. so not just going back a foreword getting 1 monster wen u have breed with it
4. inter breeding 2 make newer and bigger monsters.
(sorry for spalling dislexea) if u was looking for pointer
