Press SPACE to shoot the monsters as they come to you- the crossbow will automatically reload after 1 second. Click/drag to line up the crossbow. Hit the "hard mode" button and a third monster will appear. I will improve the game in the future and add newer versions.
The game was originally meant to be a remix of Ragdoll Archers, but after a while I realised that it would have been too complex. So I designed a crossbow that automatically reloaded after shooting (Based on the crossbow animation in Narrow.one (Poki)). Then I added a Game Over screen and it was done.
