Great game! The graphics and music work well together and it feels like a very complete and cohesive experience. Here is some more feedback after playing a bit....
- There should be a setup time, just let the player place all their spawners then that's the end of setup.
- I really liked how you integrated saving the endangered animals.
- it seems like there is no way to know when your attack is recharged, there could be a meter or something visible.
- game crashes after game over and cant be restarted
