Loot pickups and opening chests

Finals are over(thankfully) so I now have some time to work on "Path of Vision". This week I implemented opening chests and picking up loot from slain enemies. I do not have a lot of items yet, but right now it is more important that the system just works.
So for opening chests this is what I came up with:

Basically, if you stand on the square of a chest or a bag of loot your backpack will change(in this case, it turns green). You can then click on the backpack to "open" the chest/loot. This opens a new screen where you can drag and drop items from or items into.
Believe it or not, but there is some actual thought behind this system. I chose to do it this way to simulate opening a chest in real life. The chest's screen blocks your view because you are "distracted" by opening the chest just like you would be in real life.
This same system was implemented for sacks of loot enemies drop. Now all that rests is creating a system of leveling up and then adding a ton of content(items, enemies, rooms, etc.).
