Beautiful artwork, especially on the "forest" level. Could have benefitted from better sound/music, but still had those so it's a very big plus! :)
I think the game just went very easy after the lighting, should have had a LOT less ammo, I just kept pressing it and ran through the levels pretty much afterwards! :)
Maybe some hint regarding if you hit the enemy and also if they hit you, like a healthbar or something ( I'm not sure if it had health atm)
