Aiming is slow. You should move the bow as fast as your pointer moves. Also level 3 and 4 are impossible unless you have a ton of upgrades to your kit. Arrows bows and sights are all upgraded by spending your winnings but even upgrades dont help much. So since this is just a time killer game i just play lowest level and when i get bored i play somthing else. I do like that theres not a lot of adds but you do have to wait thru loading the next game which goes pretty slow.
