Your idea of arrow usage is very creative!
The graphics and the music are awsome to. I think the mechanic of this game is one of the bestis of this jam.
Maybe put the arrow key in another key works better XD. I think control the movment with the arrows key and the bow with enter key turns the shoot less precise. But i can finish this game with this configuration with no much problem too.
Congrats for the great game! I realy have very fun!
