Very fun! Visually the game looks very beautiful, and the turn-based design is engaging. It is fun to build an army of animals you've fought! I also like the visual indicators. They look very clean.
To make this game even better, I think the differences between different units can be more exaggerated. Maybe some animals can cross certain terrains while some can't (it seems that this is the case for enemy units but not for the player's units), or special abilities. It would also be cool if units don't get one-shot so easily. The game feels a bit too simplistic. It boils down to having the higher health/attack and hitting the enemy first before they hit you.
The game is very complete and very fun. The controls work perfectly, and the actions players can take and in-game information are presented very clearly, which is the most important in a turn-based strategy game. Incredible that you two managed to do all that in 10 days! Great job!
