The game was fun, I managed to get to the end of it with perfect health! I really liked how the end scene plays out after the final wave was complete. It was also great when the horde of animals ran to each enemy, and changed targets when another enemy was closer to them.
When I wanted to place some dens, I placed nests down on the ground by accident. It looks like the tree hitboxes (corners) may be overlapping the ground area. I placed dens farther away from the trees and those were fine. The endangered animals were a little difficult to see to catch them. Also, I wasn't sure about how far the spell's effectiveness was, but the animals did manage very well against the enemies without me casting it often!
