The game is great, but it's heavily buggy, sometimes inspecting certain spots doesn't give you the designated item that it's meant to, it happened to me on the catacacombs and the beast's boss fight, I sometimes manage to pick up the item but after dying, I end up losing it and I can't pick it up again from where it was.
Also when leveling up, you lose all your Health Points after equipping/unequipping an armor, it is genuinely frustrating and there is a bare-bones work-around it.
I also found a massive bug that allows you to level up without having any points, it goes in the negatives and lets you have 99 points in any Attribute, all you need to do is click fast enough, which facilitates with an auto-clicker.
