The cover is so cool. It's a nice straight forward game, I love the gameplay mechanic of throwing and teleporting into a knife and I see a HUGE POTENTIAL for this game!
It will be better if you make this as a 3D Platformer game like climbing a castle/tower/etc claiming the bags or run from bosses attacks/projectile while claiming the bags with your knife in a small area! its a huge potential and will be much more fun. T you can make the map more small and add more challanges to the map! Overall its a solid game, just need adjusting in map size and map obstacle. Love It!
