Well, I'm late again--my apologies for that! On the plus side, I believe that I have just completed this sweep of UI-work! That doesn't mean that everything is complete, please note: the main menu has yet to be themed, and I intend to deal with each minigame as they become relevant, for two examples. I also want to consider setting a font for the majority of the text (as opposed to simply using the available default, as I currently am). Nevertheless, that's fair bit of UI-work complete, I believe.
For this week's screenshots, here are two shots of the in-game "collection" UI, specifically the inventory and the physical collection. (The sword depicted in the latter is just there for the sake of having something to show--I don't yet have any actual collectables in the game.)
The inventory. I don't yet know how many inventory items are going to be available, so the size and initial number of the inventory slots may change. The inventory shown above isn't limited to just three items--it should automatically expand as new items are acquired.
The physical collection. When an item is selected, it's shown at larger scale on the right, where it can be rotated via the mouse. As mentioned above, the sword shown here is being used simply for demonstration purposes.
