Your game is very beautiful.
It was too hard for me and I feel like you should have used at least free music to add to it.
I didn't understand what the lightning spell did, it was difficult for me to face the fact that towers were aiming at the first bunny and I had no control over whether the first one was the toughest one. After c couple of buildings, the troops mixed together and I could lose everyone because the tank wasn't the target. Felt out of my control. It felt like I lost because of some random values.
It was also uncool to have my troops stand in a place around a building where they could be reached by other buildings when there are clearly safer spots that other troops have taken
