I enjoyed the atmosphere and some of the ideas. The rain of loot on the end screen is particularly funny, I really like it. The door opening animation is nice too.
I like the atmosphere and the concept of exploring the mansion to collect loot. On the other hand, I found the controls rather cumbersome. It would be smoother with “Pickup Item” mapped on something like SPACE or Left Mouse, and without opening the inventory each time you pick an item.
I encountered a bug: at one point I was attacked while opening a door, it launched a fight but returned to standard gameplay before the fight occur, and then input (move, free-Aim, ...) no longer work .
