Here's a preview of the pause menu:
Notice the new icons based on official art where possible. If I didn't have official art for an item I used the original graphics as a guide. And where there were multiple versions of the same item I tried to combine them into something new.
And, yes, that first row of items are from Vampire Killer and will be incorporated into the game.
They are as follows:
(left to right)
Map, Secret Candle, Door Key, Double Shot, Knight Shield, Mercury Boots, Gryphon Wing.
Triple Shot and Heavy Shield will also be included, but they replace their corresponding partners.
The Icons in the middle are for your regular weapons. The whips will only display the current form, but that hasn't been implemented yet. You also get to use a short sword when equipped with the Vampire Hunter outfit.
You can only swap main weapons in the menu. Sub-weapons can either be swapped in the menu or switched by pressing "select" when not in the menu.
The first heart under the clock icon for the time is lives, and the one below that is for gold. Obviously the icons for these two aren't done.
