The game feels a little strange to play. There should probably be a health bar and some moving sounds and animations would go a long way. The music choice also feels a little off. Health bars for the enemies and some feedback when they are hit would also help.
That said, the actual gameplay is enjoyable, and I had fun fighting and avoiding the attacks of the enemies. The throwing mechanic is fun to use. I liked getting a new weapon at the end of the level too, it felt like a good reward.
