Interesting concept but not really sure what the game here is.
1) The price scaling is totally off, take way too long to unlock a new dino
2) Theres no explanation that the dinos will attack each other and how this impacts score
3) No explanation of how to get points faster (I think more dinos but I' not sure and this seems counter active to having the dinos attack each other)''
4) The game functionality is laggy (Could be my pc) the camera movement is not fluid
Adaption thoughts: I think that this could be neat as an aquarium/safari management game. Somewhere that different animals are enclosed together, I wouldn't have them attack each other automatically but have some other dynamic like food built in or based on a numbers ratio between different animals.
Good on you for creating this but I think some more explanation of the mechanics would really benefit anyone looking to 'play' this.
