Will there be melee weapons like swords for a combat gameplay à la Hyper Light Drifter or will the combat be limited to ranged weapons? I love Hyper Light Drifter and would really appreciate swords in this game.

This is definitely an idea that has came up several times during development - suffice to say we're not ruling it out. If we do introduce it that will require some overall re-balancing so it'll come in a big update or not at all!
