Yes I wanna figure out how to make the arrow do damage on the way back, that is a great idea! I was also considering making the arrow pierce enemies instead of instantly recalling back, what do you think? Thanks for playing and commenting!
I feel piercing enemies would be a good addition. I am not a big fan of the instant recalling since it allows you to spam without really thinking about your arrow count making it no longer feel like a one arrow game. Forcing the player to still have to recall the arrow even after a hit would keep the one arrow feel.
