the game is fun and really creative. i really liked your creativity for example that in the start you can build the wall thats later can protect you and the shooting system was pretty satisfying. you did a good job.
one think you should do is so the player when he is fighting the monsters to be able to go through the walls because other wise he can get stuck until the monsters will come and "free him".
i would be happy if you will try and rate my game too.
