my hands were worn out after a few rounds of playing this one! have you thought about making the arrows pierce the target to make it easier to kill more enemies? you'd probably have to make the arrow hitbox a lot smaller and change the required kills to balance it out though :)
hey Gubby, haven't thought about the piercing mechanic actually but it seems ton of fun! thanks for suggesting! as for the difficulty I've received contrasting feedback which confuses me on what to do. some people found it fair, others couldn't make it to the portal. i wanted it to be challenging but not unfair.
