The biggest problem here is that you added a price tag to this.  Players are going to expect a more complete product, even if you currently have it listed as being 100% off and have "Beta" in the title.  If I had come across this on my own and picked it up, the state it is in would turn me off from picking up or playing any other games from you.  

My recommendation would be to change the "Beta" in your title to "Pre-Alpha", and remove the price tag.  You may also want to start with fewer animals to give the players a demo and let them have a feel for what the complete game will be like.  Showing how the game works with 3 to 5 animals will let players see that there is a game here to play, even if it's still in a very early alpha state.  You can then worked on adding animals slowly, without feeling quite so pressured to get it all out at once.
