The player points towards the mouse pointer. Move with WASD. Shoot arrows with space bar. Kill the axe guys who come at you from the bottom of the screen. If they touch you, game over. Enjoy!
I made everything myself, though the crossbow design is based on the Minecraft crossbow. If this gets 10 likes or favorites, I will make a v1.1, in which I will add new stuff and fix some glitches. Plz like and fav!
