for a 42mb game, this is impressive(barely). Really appreciate the smooth transition between the animations. It's really making the game feel more alive. Whoever, there's more things to be improved. The enemy AI is OK, but they still 'lock attack' you even though you shot their heads off which is abnormal. The camera while aiming is slightly bothering because you can't see the incoming enemy on left. The gameplay seems empty. All you do is find food, shoot enemy, and survive. Players will easily get bored and just delete the game. Should add missions or story mode to make the game more interesting and enjoyable.
That's just my suggestions. I understand that this game is in beta version and still in production. Good luck to the developers.
