Great but needs update

A great game dont get me wrong I loved it. But needs some stuff to keep it interesting:
- some kind of ending surprise. Maybe unlock a new secret weapon or something to reward you.
- more weapon types. There could be the ranged, heavy and light. The light could be the current weapons that they have now. The heavy could deal more damage but are slower. The ranged could be like bows, crossbows and maybe even guns.
- potions should be able to be bought more than once with the price going up for every purchase.
- you should be able to upgrade armor with various upgrades to not only add more stamina (max health) but also resistance. Where enemy hits dealt less damage per resistance point (also should be able to be upgraded when leveling up)

Thanks and I hope to see these features in an update sometime
