Great but..
The app is nice, but it needs more. Add better controls, more quests, more maps, etc. Also if you can, create some adverts so the app gets enough downloads to have more players and make the online mode be "alive". And in your other games I would take all the maps and mix it in one where you do like in this game, go to a portal (but hidden) to increase the animals strength and rewards (you must be lvl +10) and it would be on an special maps section. It will be great for the players who are already too strong and want a real challenge.
