You could update it.
Since the competition is over, you could update the instructions if you wanted to.
There are only two types of enemies, the only difference being health. The learning curve goes from ridiculously easy to hundreds of light-speed bears dogpiling on you at once. Sound effects would go a long way to improving this.
fun
Fun and entertaining but i got tired of it pretty easily
Decent
I think that there's many things you could have done to improve the game. You could have added other enemies to the game instead of just bunnies and bears. Maybe wolf or bird, shit like that. You could have also picked another gun you could get, like a machine gun, or rockets, shit like that. Overall a decent game that could use some improvement.
