What a game you've got! The calmness of your music. The cleanliness of the User interface. The smoothness of a transition! I had a very good time from this game! Keep up the good work guys!
Maybe if you add a text at the beginning to tell player what to do would be great. Otherwise it's a good game for your first time on Unity! Keep motivated!
(A group of a small goal can lead to something big :D)
We put much love into it and we're really glad you like it! (sorry for some lag after killing an enemies. It's a reference for Zed time from killing floor but with poor implement! hahaha)
