Hey there, glad you like the game!
1. Caves will eventually become nests which are a species specific mini stealth dungeon with hidden objectives and such.
2. A model for a species will just stay the same, instead we will create a large number (60ish) creatures all with different designs and styles. The goal is to give each species a unique behavior and reaction to things. We are only a small team so we cannot get super specific on things without breaking the bank.
3. More animations? Yes. Pregnancy? 100% no. Opens too many doors. Cumflation? Maybe.
Hope you stick around with our new updates and such.
