Hello i liked the idea of your game, i really tried to beat it but i couldn't beat the third phase.
I found the melee weapon useless and inconsistent with the click to attack, but maybe that's just me.
I think one of the first thing that you should have done is add a sound effect when you it the boss so we dont find ourselvs shooting at nothing wile trying to dodge everything.
And i hate the arrows XD, hope we can see an updated version of this project or a new game with this same concept.
