I had to go and read the comments to understand that he was shooting at the mirrors (a player doesn't instinctively look up, he looks straight ahead). Overall, I agree with what has been said above. You can make the balls bounce off the walls, and that takes the fun out of some of the mirrors.

Courage for the rest 

Really good implementation of the theme, It was a little confusing at first. If this ever got updated I'd hope for some audio to help game feel.

Good game, however since the wolves don't do any damage, you can just push them all to the end of the level xD
Also I notices that the bullets would bounce at anything, not only the pink glasses, so it is actually way easier to just shoot the opposing wall parallel to the ground and the bullet will come back as if you would have shot in the other direction, maybe that was unintended ?

Had to figure out that you had to shoot those pink mirror things at the top (there was no explanation inside the game). I guess holding "space" was for debugging testing. The wolves don't to any damage (at least to me). Would enjoy a line that shows me how the projectile bounces off before I shoot.

Liked those graphics.

Shooting in the mirrors is cool! You need good precision to kill a wolf!

Fun stuff: if you hold left - you beat a level and see funny animation of man flying without a horse and then teleporting on it!

Also I was confused a bit why do I die if I press space. 

Also is there only 1 level?
