My first of fps has begun with this game.... I'm loving games that have simple arcade style, DD also has simple movements and way of attack. To survive, this game needs only WASD, space, and mouseLR. Homing dagger is powerful weapon but you must survive around 150sec, so DD's first section forces learing basic skill of move aim to novice FPS player. But after learn basis, player never be allowed to depend weapon's force. Homing is limited firmly, you can shoot straight dagger unlimitedly but enemy will be spawned beyond amount of its daggers. Upgrade of the dagger is defensive preparation against endless or powerful enemy, it doesn't make this game easy. To survive longer and to beat enemies more, you must understand how to kill them quickly and smartly. After I played this game, I can play other FPS with pure fun, and also I can play DD with more fun!
