Good
Graphics were fine, and the sound was ok, and the menus were organized well. However the game play seems a little lacking, I'll admit I did not mind chomping down endless humans and some times smashing them first. Adding some destructible environment would make things interesting(Example: Military buildings that when destroyed stops production for that building until it is repaired*takes multiple hits*) Possibly adding more enemies(such as bombers, some take more then one hit, etc.)
Overall this was a good monster game, great job.
